Question

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

Answer 1

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

answer: x= 4
