Beth solved the system of equations by making a substitution for y in the second equation.

What equation did she get as a result of that substitution?

y = 4x – 11
3x + 5y = –9

A. 12x – 11 = –9
B. 12x – 55 = –9
C. 3x + 20x – 55 = –9
D. 3x + 20x – 11 = –9

can you replace the y in the second equation with what it says y is in the first equation?
that is all they want you to do.

freckles · Answer

that is just replace y in the second equation with (4x-11)
