Answer:
7
Step-by-step explanation:
The total number of video games he had to begin with is 4+10=14.
Divide the total games by 2 (cases) and you get 7 games in each case
The system of equations that models the given situation is given as follows:
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are given as follows:
- Variable x: Number of single lawns cut.
- Variable y: Number of front and back lawns cut.
He had 25 customers, hence:
x + y = 25.
He charges $15 for a single lawn and $25 for a front and back lawn, and made a total of $475, hence:
15x + 25y = 475

Answer:
(-5, 18)
Step-by-step explanation:
7x + 2(3 − 3x) = 1 simplifies to
7x + 6 - 6x = 1, which, in turn, simplifies to:
x = -5
Using y = 3 - 3x (see Step 1), we find that y = 3 - 3(-5) = 3 + 15 = 18.
Thus, the solution is (-5, 18).
