Answer:
x = 4, y = 3
Step-by-step explanation:
2x - 3y = -1
- <u>2x + y = 11</u>
-4y = -12
y = 3
solve for 'x':
2x -3(3) = -1
2x - 9 = -1
2x = 8
x = 4
factor, in mathematics, a number or algebraic expression that divides another number or expression evenly—i.e., with no remainder. For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 exactly and 12 ÷ 6 = 2 exactly. The other factors of 12 are 1, 2, 4, and 12.

Answer:
i hope its correct
Step-by-step explanation:
11x + 2y=68 ------------1
5x+y=13 ------------2
y= 13-5x. ------------3
put 3 into 1
11x +2(13-5x) =68
11x +26 -10x =68
x=42
put x =42 into 2
5(42) +y =13
210+y=13
y=13-210
y=197
the second is a negative slope due to the fact the line is going the the left and the ind variable is breakfast dep is performance
