5. 2x+y=8 ly=X-7 plz help plzzz

x=5,y=-2 or (5,-2)

Step-by-step explanation:

Here is the system of equations:

2x+y=8

y=x-7

Since we have y isolated by itself in the second equation, let's use substitution.

Substitute x-7 as y into the first equation

2x+x-7=8

combine like terms

3x-7=8

add 7 to both sides

3x=15

divide by 3

x=5

now substitute 5 as x into one of the equations to find the value of y

for example let's use y=x-7

y=5-7

y=-2

so x=5, y=-2

as a point it's (5,-2)

Hope this helps! :)
