Answer 2

ur so needy danny :P

Answer 3

(x + 20)/2 = 3x
x + 20 = 3x * 2 = 6x
x - 6x = -20
-5x = -20
x = -20/-5
= 4
x = 4

Answer 4

\[\frac{ x + 20 }{ 2 } = 3x\]Multiply both sides by 2.\[\frac{ x + 20 }{ 2 }(2) = 3x(2)\]\[x + 20 = 6x\]Combine like terms and solve for x.

Answer 5

cross multiplie

Answer 6

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