What is the solution of the system? Use substitution.
5x+y=3
6x+y=8
First, let's solve the first equation for y:
y = 3 - 5x
Now, plug this into the second equation:
6x + (3 - 5x) = 8
6x + 3 - 5x = 8
x + 3 = 8
x = 5
Now that we have the value of x, substitute it back into the first equation to find the value of y:
5(5) + y = 3
25 + y = 3
y = 3 - 25
y = -22
Therefore, the solution to the system of equations using substitution is x = 5 and y = -22.
