If there only one person then the total would be $40.25
Multiply all terms by 12/1 to get rid of fractions.
8x+2= -9x+12
Add 9x to both sides
17x+2=12
Subtract 2 from both sides
17x=10
Divide both sides by 17
x=10/17
Final answer: x=10/17
We're told x=-5 and y=11 and asked to evaluate a few expressions. That just means substitute these values into the expressions and compute the exact numerical answer.

Answer:
30
Step-by-step explanation:
5(z+4)+5(2-z) (expand parentheses by distribution)
= z(5) + 4(5) + 2(5) -z(5)
= 5z + 20 + 10 -5z
= 30
