SOLUTION: Please help me solve by substition: y=1/2x+x 2y+2x=2 So far I did this: 2(1/2x+4)+2x=2 1x+8+2x=2 3x+8=2 3x+8-8=2-8 3x=-6 x=-2 y=1/2(-2)+4 y=-1+4 y=3 Is this right? gm

: Please help me solve by substition:
y=1/2x+x
2y+2x=2
So far I did this:
2(1/2x+4)+2x=2
1x+8+2x=2
3x+8=2
3x+8-8=2-8
3x=-6
x=-2
y=1/2(-2)+4
y=-1+4
y=3
Is this right?

It's correct.
You could find that out by yourself by substituting your
answer values for x and y into the original equations.
