Question

Find the value of x in each of the following
a) 5x + 1 = 11
b) 2x - 3 = 2

Answer 1

Answer:a)2 .(b) 2.5

Explanation:

a) 5x + 1 = 11

Substract 1 from both sides

5x + 1 - 1 = 11 - 1

5x = 10

x = 10/5

x = 2.

b). 2x - 3 = 2

Add 3 to both sides

2x - 3 + 3 = 2 +3

2x = 5

x = 5/2

x = 2.5

Answer 2

Answer:x=2, x=2.5

Explanation:

5x+1=11

Subtract 1 from each side

5x=10

Divide each side by 5

x=2

2x-3=2

Add 3 to each side

2x=5

Divide each side by 2

x=2.5
