Question

Use substitution to solve the system of equations.


5x + y = –24

x + 3y = –2


A. x = –5, y = –1

B. x = 5, y = 1

C. x = –5, y = 1

D. x = 5, y = –1

Answer 1

Answer:

C (let me know if I am wrong!)

Step-by-step explanation:

We need to solve the equation.

If 5x+y = -24, then -24 - 5x = y.

x+ 3(-24-5x) = -2

= -14x-72=-2

= -14x-72+72=-2+72

= -14x=70

= -5

If x = -5, then -5 + 3y = -2.

3y = -2+5

3y = 3

y=1

So the answer is C.
