Question

y=x-7 and y=-2+5

Answer 1

What are you trying to do?

Answer 2

y=x-7
y=-2+5 . is this what u mean?

Answer 3

are you solving for x ?

Answer 4

if y=x-7
and y=-2+5
they are both equal to eachother so
x-7=-2+5
which x then equals
x=7-2+5
x=10

Answer 5

and then you can plug x=10 back into the equation to find y so
y=10-7
y=3

and to check this you can plug in y=3 to either equation
y=-2+5
(3)=3
which is correct
