Answer:
x=10
Step-by-step explanation:
5/8x - 11/2 = 3/4
Multiply each side by 8 to clear the fractions
8(5/8x - 11/2 = 3/4)
5x - 44 = 6
Add 44 to each side
5x-44+4= 6+4
5x= 50
Divide by 5
5x/5 = 50/5
x =10
Answer:x=3
Step-by-step explanation:

Simplify 5+4 to 9 and get 3x=9
Divide both sides by 3 and get x=9/3
Simplify 9/3 to 3 and get the answer x=3
