Linear Equations in one variable

Exercise 2.3

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

3x = 2x +18 3x - 2x = 18 x = 18
To check:
3x = 2x -18 3x18 =  2x18+18 54 = 36+18 54 = 54 L.H.S. = R.H.S.
Hence, it is correct.

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

5t -3 = 3t - 5 5t -3t = 5+3 2t =- 2 t= -2/2 = -1

To check:
5t 3  3t 5 5x(-1)- 3 = 3x(-1)- 5 - 5 - 3 = - 3- 5 - 8 = -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

5x + 9 = 5+3x 5x - 3x = 5- 9 2x = -4
To check:
5x 9  53x 5x(-2)+ 9 = 5 + 3x(-2) -10+9 = 5- 6 -1= -1 L.H.S. = R.H.S.
Hence, it is correct.

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

4z+3=6+2z 4z-2z=6-3 2z=3 z = 3/2

To check:
4z +3 = 6 + 2z Hence, it is correct.

Question 5:
Solve the following equations and check your results: 2x -1=14- x To check Hence, it is correct.

Question 6:
Solve the following equations and check your results:  To check: Hence, it is correct.

Question 7:
Solve the following equations and check your results:  To check:  Hence, it is correct.

Question 8:
Solve the following equations and check your results:   x=30/3 =10

To check Hence, it is correct.

Question 9:
Solve the following equations and check your results:   To check:  Hence, it is correct.

Question 10:
Solve the following equations and check your results:   To check:  Hence, it is correct.
