Question

Could somebody help me figure this out? I keep having troubles with it.
solve for x and y using substitution.
2x+4y=10
x=y-7

Answer 1

2(y-7)+4y=10 solve it

Answer 2

2x+4y = 10

X= y-7

Substitute x into the first equation,..
So

2(y-7) + 4y= 10

2y-14 +4y=10

6y = 24

Y=4

Substitute for y into x=y-7

X=4-7

** So x= -3 & y = 4

Hope this helps!
