Answer:
Below in bold.
Step-by-step explanation:
5x - 3y = 1
3x- y = 5 Multiply this equation by -3:
-9x + 3y = -15 Now add this equation to the first equation:
-4x = -14
x = -14/-4 = 3.5.
Now substitute for x in equation 1:
5(3.5) - 3y = 1
-3y = 1 - 17.5
-3y = -16.5
y = 5.5.
The degree of this expression is 6. well you have to add all the power of the variables if it's in product form.
Answer:
worked 4 hours tutoring = 4 hours * $25 = $100 earned
