This is because if he can complete 12 math problems in 6 minutes when u simplify that u get 2 problems done per minute so that would make 50 problems done in 25 minutes
Answer:
Infinite Number of Solutions
Step-by-step explanation:
Hello!
We can solve for y in the first equation, and plug that value in for y in the second equation.
<h3>Find the Equation for Y</h3>
Now that we know the equation for y, we can plug that in for y into the second equation to solve for x.
<h3>Solve for X</h3>
- x - y = -9
- x - (9 + x) = -9
- x - 9 - x = -9
- -9 = -9
Since the equations match, there are an infinite number of solutions.
If we take a close look at the equations, we can also see that they are the same equation, but with flipped signs.
