Step-by-step explanation:
9/4x + 2 = 20
To get x by it's self you do the same on both sides of the = to cancel out each side.
9/4x + 2 = 20
(Multiply 9 on both sides)
4x + 2 = 20*9
(Now subtract 2 from both sides)
4x = 20*9 - 2
And finally divide both sides by 4
x = (20*9 - 2)/4
Then solve for x as normal.
