x=12
Step-by-step explanation:
put the x at one side and the numbers ar the other
5/2x-3/4x=14+7

Answer:
$20
Step-by-step explanation:
5 copies cost $1.
25 copies cost $5.
So you have to do 100/5=$20 for 100 copies.
if the first number is x and the second number is y
1^3 = 1
2^3 =8
3^3=27
4^3 = 64
y=x^3
f(x)=x^3
