- 5y – 10x=45
- 3y + 10x = -5

y = -5; x = -2

Step-by-step explanation:

- 5y – 10x=45

- 3y + 10x = -5

Combining both equations

-8y = 40

y= 40/ -8

y = -5

Substitute y = -5 into any of the equations to get the value of x

-5 (-5) - 10x = 45

25 -10× = 45

-10x =45 -25

-10× = 20

Divide both sides by -10

x = -2
