Answer 1

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

A. 2(4y + 13) − 3y = −29
B. 2(−4y + 13) − 3y = −29
C. 2x − 3(4y + 13) = −29
D. 2x − 3(−4y + 13) = −29

Got your answer for both?

Answer 8

@UsArmy3947 for that second problem, convert them to Slope-Intercept Form (y = mx + b), then find which two lines have -7 as b (because -7 is where the two line meet, or their solution), and one slope positive while one negative slope.
The answer should be the second one, as one line is -2/5 slope and -7 intercept and the other is 7 slope with -7 intercept.
