Solve for x in the second equation and substitute it into the first equation. The result is .
A
2(x – 2y – 3) + 5y = –6B
2(x – 2y) + 5y = –9C
2(–3 + 2y) + 5y = –6D
2(–3 – 2y) + 5y = –63
To eliminate x, and then add the equations.
A
multiply the second equation by –2B
divide the second equation by 2C
multiply the first equation by 24
