Question

Please helppppppp triple sad face!!!!

Elimination method.

5x + 2y = 55
2x - y = 19

Answer 1

Ok for this, you basically want to get either the x or y alone in the end so you can solve. To make things simple, we will solve for x. This means that we want the y's to cancel out.

5x + 2y = 55
2x - y = 19

multiply 2x - y = 19 by 2 so the y's will cancel out

2x(2) - (2)y = 19(2)

this gives us

4x -2y = 38

then we simply add the two equations together!

5x + 2y = 55
+ 4x -2y = 38

9x = 93

divide by 9, and viola! your answer is x = 10 1/3

to get the y, you just put 10 1/3 in for any x and solve for the y

Answer 2

thats not it
