Question

Find the solution to the system of equations.
x=5y

2x+3y=-13

A. (-5,1)
B. (5,-1)
C. (5,1)
D. (-5,-1)

Answer 1

Answer:

D. (-5,-1)

Step-by-step explanation:

First plug in the x-value into the equation:

2(5y) + 3y= -13

Then simplify:

10y + 3y=-13

13y= -13

y= -13/13

y= -1

We have our y-value... (x, -1)

Now we have to plug in our y-value into the equation to find the x-value:

2x+ 3(-1) = -13

2x= -10

x= -5

The answer would  be (-5,-1)
