Answer:
add equation 2 from equation 3
Step-by-step explanation:
So, we are given equations 1, 2, and 3, but for this problem, we need to use just 2 and 3.
4x - 2y = -16
x + 2y = 6
In order to eliminate one variable, then we need to find whether there are two numbers that have the same coefficient (or multiply one by a number to make it) so that if you add/subtract two numbers, it gives you 0. So, in this problem, if you add
2y to -2y, then it gives you 0, which means that y would be canceled out.
So, the answer is the first option.
Feel free to ask any questions about clarity! (this explanation is pretty bad, but I can explain it more if you want) :D
