Answer:
a) x = 4
b) x = 35/2
Step-by-step 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
