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
