Find the value of x in each of the following
a) 2x – 7 = 13
b) 3x + 4 = 25

a) 10.

b) 7.

Step-by-step explanation:

a) 2x - 7 = 13                 Add 7 to both sides of the equation:

2x - 7 + 7 = 13 + 7

2x = 20

x = 10.

b) 3x + 4 = 25                 Add -4 to both sides of the equation:

3x + 4 - 4 = 25 - 4

3x = 21

x = 7.

Step-by-step explanation:

a) 2x - 7 = 13

Solution:

2x = 13 + 7

2x = 20

x = 20/2

x = 10

a) 3x + 4 = 25

Solution:

3x = 25 - 4

3x = 21

x = 21/3

x = 17

40 is the final : )
