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.
