Find the value of this expression if x = 1 and
y=-7.
xy
-9

the answer is 7/9

given..

expression is x^2y/-9

value of x=1

value of y=-7

then putting value of x and y in the given equation...

we get .

={1^2*(-7)}/-9

={1*(-7)}/-9

=(-7)/-9

=7/9

b is the final answer! : )

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
