Answer 1

a) x = 4

b) x = 35/2

Explanation:

a) (5x)/2 + 1 = 11

Subtract 1 from both sides: (5x)/2 = 10

Multiply both sides by 2: 5x = 20

Divide both sides by 5: x = 4

b) (2x)/7 - 3 = 2

Add 3 to both sides: (2x)/7 = 5

Multiply both sides by 7: 2x = 35

Divide both sides by 2: x = 35/2 = 17.5
