The answer is x= 14 since the angles are supplementary
The solution of the equation is given by (-2,-1), This is represented by option C.
<h3>What is a System of Equations?</h3>
A system of equations is a set of equation that have a common solution.
The solution of the equations can be determined by using the Elimination and Substitution method
3x-5y = -1
2x-y = -3
-7x = 14
x = -2
Substituting this value in the equation
3 * (-2) -5y = -1
-6 -5y = -1
-5y = 5
y = -1
Therefore, the solution of the equation is given by (-2,-1), This is represented by option C.
