Question

Is this written in standard form -7x-10y=40

Answer 1

-7x - 10y = 40
-7x + 7x - 10y = 40 + 7x
               -10y = 40 + 7x
               -10        -10
                    y = -4 - ⁷/₁₀x

Answer 2

NO, it's not you have to move the  negative 7 to the other side wich makes it positive so you will be left with -10y=7x+40  so then you divide everything by -10
so then  it will be y=7/-10x+40/-10
so the final answer will be y=7/-10-4
