Bring the xs to one side and the numbers to the other by subtracting x and adding 6 to both sides. Then you have 3x = 36, so x=12

solve your equation step-by-step.
x+30=4x-6
Subtract 4x from both sides.
x+30-4x=4x-6-4x
-3x+30=-6
Subtract 30 from both sides.
-3x+30-30=-6-30
-3x=-36
Divide both sides by - 3.
-3x/-3 = - 36/-3
x=12
