It is: x-1+4+7x-3 = 8x simplified
8x
-8x+7 = -7x-2 -8x = -7x-2-7 -8x=-7x-9 -8x+7x=-9 -1x=-9 x=-9/-1 x=9
Organize this expression into groups of like terms, so that it is easy to combine.7x^2 - 8x + 2x - x^3 + 9 - 8Answer:7x^2 - 6x -x^3 + 1
8x=7x-7 x=-7
Do you mean 6x+7x-8x if so it is 5x because 13x-8x = 5x
It is: 7x
x=3
28=8x+12-7x 28=8x-7x+12 28=x+12 28-12=x+12-12 16=x
8x-2 = -9+7x8x-7x = -9+2x=-7
7x+x = 8x
Try to factor the left side and set each of the linear expressions equal to zero. 7x^2 +8x -12= 0 (7X-6)(X+2)=0 7X-6=0 X=6/7 X+2=0 X=-2
