Reduce the numbers with 3. Any expression divided by 1 remains the same.
The answer is C. This would make the total cost 90 dollars without paying for a membership card or shipping.
We are given:
Our goal in solving for any variable, in this case is x, we need to isolate x on one side of the variable. Let's start by subtracting 7x from both sides, which will cancel the +7x on the right side. We are then left with:
Now, we want to move that +10 to the other side so our x is all by itself. Let's subtract 10 from both sides, which will cancel the +10 on the right leaving us with:
Since we cannot have a coefficient when solving for x, we need to divide both sides by -3.
When we divide, our answer is:

Answer:
Step-by-step explanation:
x² + 3 = (-9)² + 3 { (-9)² = -9 *-9 = 81}
= 81 + 3
= 84
x + 6 = -9 + 6 = -3
