-8x+7 = -7x-2 -8x = -7x-2-7 -8x=-7x-9 -8x+7x=-9 -1x=-9 x=-9/-1 x=9
if its x(squared) its 7x(cubed) if its 2xX its 14x(squared)
8x-1 = 7x+2 Add 1 to both sides: 8x = 7x+3 Subtract 7x from both sides: 1x = 3 ie x = 3
3x + 4x = 7x
I is -8x^2.
The GCF is 9. The LCM is 3528.
-8x+7 = -7x-2 -8x = -7x-2-7 -8x=-7x-9 -8x+7x=-9 -1x=-9 x=-9/-1 x=9
8x=7x-7 x=-7
Do you mean 6x+7x-8x if so it is 5x because 13x-8x = 5x
It is: 7x
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
X squared + 7X + 12?
The LCM of 8x and 25y is 200xy
x = 4 You have to add the 8x and 7x to get 15x and then divide 60 by 15 to get x by itself.
If you mean: 5x(3x+2)-8x-7x then the expression can be simplified to 15x^2 -5x
