An equation is formed from two equal expressions. Carmen earns $390 for her 13 hours of tutoring.
Equation: An equation is created by equating two equations with an equal sign '='.
Let's say Carmen is earning $30 per hour of her tutoring her.
Therefore, the formula for Carmen's income after H hours of tutoring can be written as:
Income = hourly wage for individual instruction x number of hours
I = 30 × H
I = 30H
After 13 hours of tutoring, Carmen's income will be:
I = 30 (13)
I = 390
So, after 13 hours of tutoring, Carmen's income will be $390.

Answer: x=3.6; y=-2.5
Step-by-step explanation:
To solve this pair of equations, we can use elimination method.
5x+4y=8
10x-4y=46
Add both equations together to cancel out 4y.
15x=54 [divide both sides by 15]
x=3.6
Now that we know x, we can plug it back into any equation to find y.
5(3.6)+4y=8 [multiply]
18+4y=8 [subtract both sides by 18]
4y=-10 [divide both sides by 4]
y=-2.5
Now, we have x=3.6 and y=-2.5.
