If you set the two equations equal to each other, then solve for x, and then you substitute your answer into one of the equations you will get your solution. 8x+4=10x-6 4=2x-6 10=2x 5=x 10(5)-6=44 8(5)+4=44 44 IS YOUR ANSWER.
10. 4w^2 + 7w^2 + 7z^2
Combine each term with the same variable.
11w^2 + 7z^2
This is in simplest form.
11. 3x + 4(5x + 2)
Multiply each term inside the parentheses by 4.
3x + 20x + 8
Combine all the terms with the same variable.
23x + 8
This is in simplest form.
