Question

How do i use the substitution method to solve y=x+2 and 2x+y=8

Answer 1

2x+(x+2)=8
3x=6
x=2

Answer 2

substitute y=x+2 in 2x+y=8

2x+(x+2)=8
3x=6
x=2

Answer 3

You have two equations

y = x + 2 ->1

2x + y = 8 ->2

Now put the value of y in 1 in 2

2x + (x +2 ) = 8
3x =6
x =2

Then put x in 1

y = (2)+2
y=4

Answer 4
