We need to use simple division to solve the problem. The number of students in the painting class this month is 14.
It is said that each student pays $12 for class and $28 for materials. The total amount paid by each student can be calculated by adding both of them. We know that the total amount this month is $560, we need to find the number of students in the class. Let us consider the number of students in the class to be x, and multiply the total amount per student to x and equate it to 560.
(12+28)x=560
40x=560
x=560/40=14
Therefore the number of students in the painting class is 14.

Answer:any number is correct
Step-by-step explanation:
4(3x+1)=12x+4
12x+4=12x+4
12x-12x=4-4
0=0
This equation has no answer.
Actually any number you put in place of x this equation will be true so we can say the answer is
X=infinity
To solve for n start off by adding bn to both sides.
an - 4a + 3 + -bn = bn + -bn
an - bn - 4a + 3 = 0
Now, add -3 to both sides.
an - bn - 4a + 3 + -3 = 0 + -3
an - bn - 4a = -3
Add 4a to both sides.
an - bn - 4a + 4a = -3 + 4a
an - bn = 4a - 3
Factor out variable n.
n(a-b) = 4a - 3
Divide both sides by a - b.
a(a-b) / a - b = 4a - 3 / a - b
Your final answer is:
n = 4a - 3 / a - b
