2(5x+7)+8x-7=27

We move all terms to the left:

2(5x+7)+8x-7-(27)=0

We add all the numbers together, and all the variables

8x+2(5x+7)-34=0

We multiply parentheses

8x+10x+14-34=0

We add all the numbers together, and all the variables

18x-20=0

We move all terms containing x to the left, all other terms to the right

18x=20

x=20/18

x=1+1/9

2x (y^2+3)-5 (3+y^2)

Irina18 [472]

Use distributive property a(b + c) = ab + ac.

$2x(y^2+3)-5(3+y^2)=(2x)(y^2)+(2x)(3)+(-5)(3)+(-5)(y^2)\\\\=2xy^2+6x-15-5y^2$
