Answer:
Here's how:
Step-by-step explanation:
Let's say you have:
2x + y = 2
x - 4y = -12
To solve, eliminate a variable to solve for the other variable. In this case, let's multiply the second equation by -2 so that we can eliminate x.
2x + y = 2
-2x + 8y = 24
Now combine these equations:
9y = 26
y = 2.888
Now solve by putting 2.888 for y into the original equation.
2x + 2.888 = 2
Subtract 2.888 from both sides to isolate x.
2x = -0.888
x = -0.444
I'm really sorry that I couldn't pick clean numbers, I hope this helps anyway!
