Solve for system of equations −3y−4x=−11 3y−5x=−61

1 answer:

6 0

X= 8
Y= -7

If you use elimination:

–3y–4x=–11
3y–5x=–61

Add the two equations and get

–9x=–72

Divide by –9 on both sides

X=8

Substitute 8 in for x

–3y–4(8)=–11

Simplify

–3y–32=–11

Add 32 on both sides

–3y=21

Divide by –3 on both sides

Y=–7
