It is solve with rules of algebra which say: Anything I do to one side of an equation, I must do to the other side First, subtract 8 from both sides 4x + 8 - 8 = -4 -8 do the subtraction 4x = -12 divide both sides by 4 do the division this is the solution You can check it by putting it back into equation 4*(-3) + 8 = -4 -12 + 8 = -4 -4 = -4 checks OK
