2:y=1, x=6
3:x=5 and y=1
Step-by-step explanation:
For #1: Use substitution, substitute x=2 into the second equation
For #2: Set the two equations equal to each other and solve for y. Then plug in the value of y and solve for x.
For #3: Use substitution, substitute x=2y+3 into the second equation. Solve for y and plug in the value of y to solve for x.
