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:
d = 4de - 7
Step-by-step explanation:
7 - d = 4de - 2d
7 = 4de - 1d
7 - 4de = -1d
-7 + 4de = d
I don't get because you did not add a symbol between 110 and 7/16 so i can't tell you.
The steps for substitution are step 1 solve for the equation x = or y then step 2 is substitute the solution from step 1 into the second equation and step 3 is solve the new equation for x.
