Answer:
7. x=18 8. x=4
Step-by-step explanation:
Question 7: Solve for x
Expand: 5x-30=3x+6
Add 30 to both sides: 5x-30+30=3x+6+30
Simplify:5x=3x+36
Subtract 3x from both sides:5x-3x=3x+36-3x
Simplify: 2x=36
Divide by 2: 2x/2=36/2
x=18
(Sorry, to tired to explain how I got #8's answer. Hope this helped)
