Question

Checking some math work to make sure i got the right answers!!
If you were to use the substitution method to solve the following system, choose the new equation after the expression equivalent to x from the second equation is substituted into the first equation.

2x − 3y = −29
x + 4y = 13

2(4y + 13) − 3y = −29
2(−4y + 13) − 3y = −29
2x − 3(4y + 13) = −29
2x − 3(−4y + 13) = −29

i got 2(−4y + 13) − 3y = −29

Answer 1

y=5, x=-7
