Solve for x:... 5x-12=2x

Solve for x:... 3x-2=-17

(-2)^3=

Solve for y:... y/3+4=-5

5x-2x-12=2x-2x... 3x-12=0... 3x-12+12=0+12... 3x=+12... Divide both sides…

Add 2 to both sides... 3x=-15... x=-5

(-2)(-2)(-2)... =+4(-2)... =-8

We cannot divide 1/3 easily, so we simplify everything else fi…

Solve for x:... 5x-12=2x

5x-2x-12=2x-2x... 3x-12=0... 3x-12+12=0+12... 3x=+12... Divide both sides…

Solve for x:... 3x-2=-17

Add 2 to both sides... 3x=-15... x=-5
