Combine like terms:

-3x^2+2x-4x^2-9+6x-2x^2+8

Solve for x:

8x-11= -11x+18

Solve for x:

-2(x-5)+7=z-8-5x

Solve for x:

(x-2)/5 - 3/2= (x+1)/10

Translate to an algebra statement; do not solve:

Seven times the difference of six and a twice a number yields the same result as the same number decreased by one.

I will be happy to critique your work. To solve for x, combine the terms that include x on one side and the constants on the other.

"Combining" like terms" means separately combining the terms with different powers of x, and the constants.

I can answer 3x^2+2x-4x^2-9+6x-2x^2+8

first you want to combined all the squared problems whch is : 3x^2 -4x^2-2x^2

Since two negatives make a positive : 3x^2-4x^2 =7x^2

now subtract -2x^2 and that leaves for 5x^2

Now you combine all the numbers with variables : 2x +6x = 8x

so now we have

5x^2+ 8x

now we combine all the constant numbers -9+8= -1

answer 5x^2+8x -1
