User: -5x + x + 9 = -4x + 12

Weegy: The answer is x=-6,2. [ x^(2)-12=-4x Since -4x contains the variable to solve for, move it to the left-hand side of the equation by adding 4x to both sides. x^(2)-12+4x=0 Reorder the polynomial x^(2)-12+4x alphabetically from left to right, starting with the highest order term. x^(2)+4x-12=0 In this problem 6*-2=-12 and 6-2=4, so insert 6 as the right hand term of one factor and -2 as the right-hand term of the other factor. (x+6)(x-2)=0 Set each of the factors of the left-hand side of the equation equal to 0. x+6=0_x-2=0 Since 6 does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 6 from both sides. x=-6_x-2=0 Set each of the factors of the left-hand side of the equation equal to 0. x=-6_x-2=0 Since -2 does not contain the variable to solve for, move it to the right-hand side of the equation by adding 2 to both sides. x=-6_x=2 The complete solution is the set of the individual solutions. x=-6,2 ]

-5x + x + 9 = -4x + 12;

-4x + 9 = -4x + 12;

-4x + 4x = 12 - 9;

0 = 3

For equation -5x + x + 9 = -4x + 12, there is no solution that exists.
