The solution to the system of equations is (-4,7)
Step-by-step explanation:
Given that the system of equations is
and

Using substitution method, we shall solve the system of equations.
From the equation
, let us determine the value of the y.
Thus, we have,

Now, substituting
in the equation
, we get,

Adding the like terms, we get,

Subtracting both sides by 3, we have,

Dividing both sides by -2, we have,

Now, substituting
in the equation
, we get,

Adding both sides by 4, we get,

Thus, the solution to the system of equations is (-4,7)
