Question

Solve the system of equations.
- 5y + 8x = -18
5y + 2x = 58
х=
y =

Answer 1

x = 4 and y = 10

Explanation:

-5y + 8x = -18

5y + 2x = 58

First you will want to get rid of y from both equations, so you add both equations together.

You will get 10x = 40, then subtract 10 from both sides and you get x = 4.

Now substitute x as 4 in any of the equations to get y.

-5y + 32 = -18

-5y = -50

y= 10

Answer:

x = 4

y = 10
