Answer:x=2, x=2.5
Step-by-step 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
Answer:a)2 .(b) 2.5
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
