What is 4-2x+8+5x simplified

4-2x+8+5x

-2x - 2x

4 + 8 + 3x

12 + 3x

Answer: it is 3 • (x + 4)

Step-by-step explanation: We move all terms to the left:

4-2x+8 - (+5x) = 0

We add all the numbers together, and all the variables

-2x - (+5x) + 12=0

We get rid of parentheses

-2x-5x+12=0

We add all the numbers together, and all the variables

-7x+12=0

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

-7x=-12

x=-12/-7

x=1+5/7We move all terms to the left:

4-2x+8 - (+5x) = 0

We add all the numbers together, and all the variables

-2x - (+5x) + 12=0

We get rid of parentheses

-2x-5x+12=0

We add all the numbers together, and all the variables

-7x+12=0

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

-7x=-12

x=-12/-7

x=1+5/7
