Answer :
3(x - 5) = 8x - 30
Distribute 3 into the parenthesis:
3x - 15 = 8x - 30
Add 15 to both sides:
3x = 8x - 15
Subtract 8x to both sides:
-5x = -15
Divide -5 to both sides:
x = 3
Distribute 3 into the parenthesis:
3x - 15 = 8x - 30
Add 15 to both sides:
3x = 8x - 15
Subtract 8x to both sides:
-5x = -15
Divide -5 to both sides:
x = 3
C. x=3 because you need to distribute the 3 to the x and the -5. This will get you 3x-15= 8x-30. Then, you have to subtract 3x from both sides. -15=5x-30. Lastly, you add 30 to both sides. 15=5x. Divide both sides by 5 and you have x=3.
