Question

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

x = 10

x = 4

x = -14

x = -17

Answer 1

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
