First, solve −2x=−14y+82 for x by dividing each side by -2 -2x ÷ -2 = [tex] \frac{-14y + 82}{-2} [/tex] x=7y−41
Substitute 7y−41 for x in −9x=−14y+26 −9(7y−41)=−14y+26
Simplify each side −63y+369=−14y+26
Add 14y to each side −63y+369+14y=−14y+26+14y −49y+369=26
Add -369 to each side −49y+369+−369=26+−369 −49y=−343
Divide each side by -49 -49y ÷ -49y = -343 ÷ -49 y = 7 ============================================================ Substitute 7 for y in x=7y−41 x=(7)(7)−41 x = 8
