Question

Consider the system of equations.

3x − y = 5,

2x + 3y = −15

1. Which value can the first equation be multiplied by to form opposite values on the y-term?
A.-3
b.-2
c.3
d.4
The solution to the system of equations is _
A.-5,0
B. 5,0
C.0,-5
D.0,5
.

Answer 1

1. C 2 .c hope this helps good luck

Answer 2

1. c (multiply by 3 to get 9x - 3y = 15)
2. c (add the new top expression with the bottom one to get 11x = 0) substitute 0 into either equation to get -5)

hope this helps!
