Answer: x = 3
Step-by-step explanation:Simplifying
12 + 5x = 18 + 3x
Solving
12 + 5x = 18 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
12 + 5x + -3x = 18 + 3x + -3x
Combine like terms: 5x + -3x = 2x
12 + 2x = 18 + 3x + -3x
Combine like terms: 3x + -3x = 0
12 + 2x = 18 + 0
12 + 2x = 18
Add '-12' to each side of the equation.
12 + -12 + 2x = 18 + -12
Combine like terms: 12 + -12 = 0
0 + 2x = 18 + -12
2x = 18 + -12
Combine like terms: 18 + -12 = 6
2x = 6
Divide each side by '2'.
x = 3
Simplifying
x = 3

Answer:
Polynomial Function: 3.5n + 1
Total Price of the Apples: $32.50
Step-by-step explanation:
The polynomial function is 3.5n + 1:
The 3.5n comes from the $3.50 it costs to buy an apple, and the n comes from the amount of apples bought. The 1 then comes from the tax that is added onto the price.
The total price of the apples:
3.5n + 1 ; n = 3^3 = 9
(3.5 x 9) + 1
31.5 + 1
32.5
$32.50
