Question

HELP PLEASE . Help solve while using elimination method!!!!

Answer 1

I will do #1 to show you how to solve these:

Equation 1: 2x + y = 6 → -1(2x + y = 6) → -2x - y = -6

Equation 2: 3x + y = 10 → 1(3x + y = 10) → 3x + y = 10

Now that one of the variables (y) has the same coefficient but opposite signs, we can add the two equations together to eliminate "y":

-2x - y = -6

+ 3x + y = 10

x = 4

Now that we know that x = 4, we can plug "4" in for "x" into Equation 1 or 2 to solve for "y". I am going to use Equation 1

Equation 1: 2x + y = 6 → 2(4) + y = 6 → 8 + y = 6 → y = -2

Answer: x=4, y=-2

NOTE: You can plug both x and y into the other equation to check that your answer is correct.
