 Solve the following equations and check your results: 3x = 2x +18
 Answer 1:

3x = 2x +18
NCERT Solution (EX - 2.3) - Chapter 2: Linear Equations in one variable, Maths, Class 8 Notes - Class 8 3x - 2x = 18
NCERT Solution (EX - 2.3) - Chapter 2: Linear Equations in one variable, Maths, Class 8 Notes - Class 8 x = 18
To check:
3x = 2x -18
NCERT Solution (EX - 2.3) - Chapter 2: Linear Equations in one variable, Maths, Class 8 Notes - Class 8 3x18 =  2x18+18
NCERT Solution (EX - 2.3) - Chapter 2: Linear Equations in one variable, Maths, Class 8 Notes - Class 8 54 = 36+18
NCERT Solution (EX - 2.3) - Chapter 2: Linear Equations in one variable, Maths, Class 8 Notes - Class 8 54 = 54
NCERT Solution (EX - 2.3) - Chapter 2: Linear Equations in one variable, Maths, Class 8 Notes - Class 8 L.H.S. = R.H.S.
Hence, it is correct.

Question 2:
 Solve the following equations and check your results: 5t - 3 = 3t - 5

Answer 2:
5t -3 = 3t - 5
NCERT Solution (EX - 2.3) - Chapter 2: Linear Equations in one variable, Maths, Class 8 Notes - Class 8 5t -3t = 5+3
NCERT Solution (EX - 2.3) - Chapter 2: Linear Equations in one variable, Maths, Class 8 Notes - Class 8 2t =- 2

NCERT Solution (EX - 2.3) - Chapter 2: Linear Equations in one variable, Maths, Class 8 Notes - Class 8 t= -2/2 = -1

To check:
5t 3  3t 5
NCERT Solution (EX - 2.3) - Chapter 2: Linear Equations in one variable, Maths, Class 8 Notes - Class 8 5x(-1)- 3 = 3x(-1)- 5
NCERT Solution (EX - 2.3) - Chapter 2: Linear Equations in one variable, Maths, Class 8 Notes - Class 8 - 5 - 3 = - 3- 5
NCERT Solution (EX - 2.3) - Chapter 2: Linear Equations in one variable, Maths, Class 8 Notes - Class 8 - 8 = -8
NCERT Solution (EX - 2.3) - Chapter 2: Linear Equations in one variable, Maths, Class 8 Notes - Class 8 L.H.S. = R.H.S.
Hence, it is correct.

Question 3:
 Solve the following equations and check your results: 5x 9  53x

Answer 3:
5x + 9 = 5+3x
NCERT Solution (EX - 2.3) - Chapter 2: Linear Equations in one variable, Maths, Class 8 Notes - Class 8 5x - 3x = 5- 9
NCERT Solution (EX - 2.3) - Chapter 2: Linear Equations in one variable, Maths, Class 8 Notes - Class 8 2x = -4
To check:
5x 9  53x
NCERT Solution (EX - 2.3) - Chapter 2: Linear Equations in one variable, Maths, Class 8 Notes - Class 8 5x(-2)+ 9 = 5 + 3x(-2)
NCERT Solution (EX - 2.3) - Chapter 2: Linear Equations in one variable, Maths, Class 8 Notes - Class 8 -10+9 = 5- 6
NCERT Solution (EX - 2.3) - Chapter 2: Linear Equations in one variable, Maths, Class 8 Notes - Class 8 -1= -1
NCERT Solution (EX - 2.3) - Chapter 2: Linear Equations in one variable, Maths, Class 8 Notes - Class 8 L.H.S. = R.H.S.
Hence, it is correct.

Question 4:
 Solve the following equations and check your results: 4z +3 = 6 + 2z

Answer 4:

4z+3=6+2z

NCERT Solution (EX - 2.3) - Chapter 2: Linear Equations in one variable, Maths, Class 8 Notes - Class 84z-2z=6-3
