4x-3x+5200=4x+400
Multiply both sides of the equation by 4.
x+5200=4x+400
Combine 4x and -3x to get x.
x+5200-4x=400
Subtract 4x from both sides.
-3x+5200=400
Combine x and -4x to get -3x.
-3x=400-5200
Subtract 5200 from both sides.
-3x=-4800
Subtract 5200 from 400 to get -4800.
x=\frac{-4800}{-3}
Divide both sides by -3.
x=1600
Divide -4800 by -3 to get 1600.
