Question

PLEASE HELP !!!!!!!!Solve the system of equations using the linear combination method.

{9x+5y=35
2x+5y=0

Answer 1

The solution would be (5, -2)

Explanation:

To use this method, start by multiplying the second equation by -1. Then add the two equations together.

9x + 5y = 35

-2x - 5y = 0

------------------

7x = 35

x = 5

Now that we have the value of x, use it to solve either equation for y.

2x + 5y = 0

2(5) + 5y = 0

10 + 5y = 0

5y = -10

y = -2
