Answer:
Each pack of gum costs $3
Step-by-step explanation:
We can set up the equation:
Answer: (4+1)+(-10+13)=5n+3
(4+1/11)+(-10+13)=45n+3
Step-by-step explanation:
Let the numbers be x and y, then
2x + y = 47 . . . (1)
x + 3y = 56 . . . (2)
(2) x 2 => 2x + 6y = 112 . . . (3)
(1) - (3) => -5y = -65 => y = -65/-5 = 13
From (2), x + 3(13) = 56 => x = 56 - 39 = 17
The two numbers are 13 and 17.
Answer:
y = 8
Step-by-step explanation:
Step 1: Write out equation
13 + 3y = 37
Step 2: Subtract 13 on both sides
3y = 24
Step 3: Divide both sides by 3
y = 8
X=0. Y=-2. There is only one x value for this question.
