Y=3x - 2
Y=-1/2x + 5
Substitution method means to substitute x or y from one equation into the other equation. In this case, since both equations are in "Y= " format, set them equal to each other:
3x - 2 = -1/2x + 5
Some people don't like fractions, so to clear the fractions, multiply both sides by 2:
Add +x from each side, and add +4 to each side to get all x terms to the left side and the number terms to the right side:
If , substitute into the first equation:
Check in the second equation:
Y=-1/2x + 5
