10x - 5y = 5
-20x + 6y=-22
this is elimination how do i doit

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

answer: 1475
