5x-16=3x Found 2 solutions by Earlsdon, checkley71:Answer by Earlsdon(6294) (Show Source):
You can put this solution on YOUR website! Solve for x: The idea is to get the x onto one side of the equals sign. Start by subtracting 3x fom both sides of the equation. Now add 16 to both sides. Finally, divide both sides by 2.
Check: Set x = 8 in the original equation. Simplify. It checks!
You can put this solution on YOUR website! 5X-16=3X OR SUBTRACTING 3X FROM BOTH SIDES OF THE EQUATION WE GET
5X-3X-16=3X-3X OR 2X-16=0 NOW ADD 16 TO EACH SIDE WE GET
2X-16+16=0+16 OR 2X=16 NOW DIVIDE BOTH SIDES BY 2 WE GET
(2X)/2=16/2 OR X=8
PROOF 5*8-16=3*8 OR 40-16=24 OR 24=24
