Answer:
One solution. (C)
Step-by-step explanation:
Use substitution to solve the problem:
Since we know y is basically 3 less than x, we can plug that into the second equation.
4x-10(x-3)=6
After solving this we get:
x=4. We can plug this into the first equation.
y=4-3
y=1
There is only one solution.
