You can put this solution on YOUR website! start with:
-7x + 8 + 4x = -25
combine like terms to get:
-3x + 8 = -25
subtract 8 from both sides of the equation to get:
-3x = -33
divide both sides of the equation by -3 to get:
x = 11
substitute in the original equation to get:
-7(11) + 8 + 4(11) = -25
simplify to get:
-77 + 8 + 44 = -25
combine like terms to get:
-77 + 52 = -25
combine further to get:
-25 = -25 confirming the solution is good.
