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:
Let the cost of one brownie,
cost of one cookie
Times on both sides on the second equation above to get the following:
To find the value of , use substitution:
the cost of a brownie is $
