3x-5y=8 2x+5y=22
Solve second equation for x; first subtract 5y from each side.
2x=-5y+22 (Divide by 2)
x=-5/2y+11 (Substitute into x into the first equation)
3 (-5/2y+11)-5y=8 (Simplify
)
-15/2y +33-5y=8 (Combine like terms)
-25/2y+ 33=8 -25/2y=-25 (Divide each side by -25)
1/2y=1 y=2 Therefore 3x-5(2)=8 3x-10=8 3x=18 x=6
x=6, y=2
- Hope this helps!
