4 times what equals 9. Well let's do this backwards. 9/4 equals 2.25 or 2 1/4 and 2 1/4 + 3 = 5 1/4. x=5 1/4. 4(5 1/4 - 3) = 9. Hoped I helped!
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
38 is the answer. 25 cents + 10 cents + 3 cents
