If A=3x^2 + 5x - 6 and B= -2x^2 - 6x + 7 than A - B equals...?

5x^2 +11x -13

Step-by-step explanation:

A=3x^2 + 5x - 6 and B= -2x^2 - 6x + 7

A- B =3x^2 + 5x - 6 -( -2x^2 - 6x + 7)

Distribute the minus sign

A- B = 3x^2 + 5x - 6 +2x^2 + 6x - 7

Combine like terms

      = 5x^2 +11x -13

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
