Answer:
A
Step-by-step explanation:
Answer: $9.71
Step-by-step explanation: Just subtract the pizza amount (8.50) and the drink (1.79) from the $20.
First you subtract two from both sides.
2x+2=-2
2x -2=-4
2x=-4 (because the two in the middle cancels out because you subtracted it. subtracting from the other side keeps it a negative since it's already in negative territory.)
Then you divide by 2 with the numbers remaining.
2x=-4
divided by 2 =
x=-2.
