Could someone show me how to do this? The instructions say "Solve each of the following systems of equations by substitution. Check the solution by replacing the ordered pair into both equations." And this is the first problem
y=3x
x+y=8
My guess is that it would be like this...
For Y: y=3(0)
y=0
For X: 0=3x
x=3 (that may be wrong)
For Y: 0+y=8
y=8
For X: x+0=8
x=8
This is what we were doing earlier, but I don't understand how we're supposed to check the solution
