Question

Solve for x: the quantity of x plus 20 over 2 = 3x

Answer 1

x + 20/2 = 3x
What do you think you need to do first?

Answer 2

I honestly have no Idea

Answer 3

Okay. First you need to multiply both sides by 2 to get rid of the 2.

Answer 4

2(x+20/2) = 3x(2)
Then the 2's cancel eachother out on the left side
x+20=6x
Then you want to get rid of the x's on the same side
so you would subtract x from eachside
20=5x
divide both sides by 5 to get x on its own
20/5 = 5x/5
4=x
