Drop the 4 down to make it equal to 2.
one is the biggest common multiple. multiplying into 2 twice and 3 three times.
Answer: x=-4, y=-7
Problem:
4x-6y = 26
5x-4y=8
You can use substitution or elimination to solve the problem. I’m going to use elimination.
Multiply by -2 => -8x+12y = -52
Multiply by 3 => 15x- 12y = 24
Add those equations together:
7x=-28
x=-4
Plug that into one of the original equations to get y.
4(-4)-6y=26
-16 - 6y=26
-6y=42
y=-7
Check for the other equation to see if this is true. Which in this case it is. So that’s your answer. x=-4, y=-7
The maximum number of shirts I can buy is 2.
14.50 x 2 = 29
14.50 x 3 = 43.5
Two shirts cost 29 dollars, and 3 shirts cost 43.5 dollars. Since $43.5 is higher than the money I currently have, I can only buy 2 shirts.
