Answer:
x = 5, y = 2
Step-by-step explanation:
First, find the value of x in respect to y:
2x + 3y = 16
2x = 16 - 3y
x = 8 - 3/2y
Then, substitute this expression into the second equation (Since we've established x is equal to 8 - 3/2y, we can put that in place of x):
4(8 - 3/2y) + 10y = 40
Then, distribute and solve for y:
32 - 6y + 10y = 40
32 + 4y = 40
4y = 8
<u>y = 2</u>
Now that we know what y equals, we can substitute the value of y in the equation to find x:
2x + 3(2) = 16
2x + 6 = 16
2x = 10
<u>x = 5</u>
8 sodas X $1.59 =$12.72 per week
$12.72 per week X 4 weeks per month =$50.88
$50.88 X 12 months per year = $610.56 per year
Answer:
4
Step-by-step explanation:
Answer: x=8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3x−x−1=15
3x+−x+−1=15
(3x+−x)+(−1)=15(Combine Like Terms)
2x+−1=15
2x−1=15
Step 2: Add 1 to both sides.
2x−1+1=15+1
2x=16
Step 3: Divide both sides by 2.
2x
/2
=
16
/2
x=8
