Answer:
-5
Step-by-step explanation:
x = first number
y = second number
From the first sentence
11 = 2x + 3y
From the second sentence (I'm assuming the word "dust" should be "first"
y = 2-x
rewritten as
x + y = 2
So your system of equations is
2x + 3y = 11
x + y = 2
Multiply the 2nd equation by -2
2x + 3y = 11
-2x - 2y = -4
Add the two equations together
y = 7
Use y=7 to solve for x
x = 2-y = 2-7 = -5
