The system of equations according to the given information is the following:
x=7+y
3x+2y=96
There are multiple ways to solve this, but using addition is probably the fastest. Rearrange the equations into corresponding formats like this:
x-y=7
3x+2y=96
Then match the coefficients of one of the variables:
2x-2y=14
3x+2y=96
Then add the two equations together to find x:
5x=110
x=22 cars
So Leonard has 22 cars, and since he has seven more cars than Liam, Liam has 15 cars.
Answer:
y=2
Step-by-step explanation:
First, you substitute x with 2.
3(2)-6y=(-6)
Then, you multiply:
6-6y=(-6)
Next, you subtract 6 from -6. So, the first 6 gets crossed out because of inverse of operation.
-6y=-12
Finally, you divide -6 to both sides of the equation to get y=2
