6x + 5y = 147
8x + 4y = 156

Answers

Answer 1
Answer:

Answer:

[12, 15]

Step-by-step explanation:

{6x + 5y = 147

{8x + 4y = 156

-¾[8x + 4y = 156]

{6x + 5y = 147

{-6x-3y=-117← New Equation

________________

2y = 30

______

22

y = 15 [Plug this back into both equations to get the x-coordinate of 12]; 12 = x

So, using the Elimination Method, what I did here was took the bottom equation and multiplied it by -¾, turning 8x to -6x, canceling out all x-terms.It does not matter which variable you choose to eliminate, as long as you know what you are doing.

I am joyous to assist you anytime.
