10x - 5y = 5

-20x + 6y=-22

this is elimination how do i doit

Answer: The answer is 3 and 2

Step-by-step explanation: multiply the first equation by 2

Multiply the second equation by 1

U get: 20x - 10y = 10

- 20x + 6y = - 22

Adding the equation

Note: 20x + (-20x) = 0 meaning it has been eliminated

Now we have only: - 10y + 6y = 10 - 22

Giving: - 4y = - 12

Divide both sides by - 4

We have: y = 3

Substitute the value of y into equation 1

10x - 5 (3) = 5

10x - 15 = 5

Collect like terms

10x = 5+15

10x = 20

Divide both sides by 10

x = 2

Hence; y=3; x=2
