My question is what is 7+6x=3x+3+4x

7+6x= 3x+3+4x

7+6x= 3x+4x+3

7+6x= 7x+3

move +7x to the other side

sign changes from +7x to -7x

7+6x-7x= 7x-7x+3

7-x= 3

Move 7 to the other side.

Sign changes from +7 to -7.

7-7-x= 3-7

-x= -4

Multiply by -1

-1(-x)= -1(-4)

x= 4

x= 4

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.
