6x + y = x + 5y
5x = 4y
4x + 6x + y = 180
10x + y = 180 so y = 180 - 10x
substitute y = 180 - 10x into 5x = 4y
5x = 4y
5x = 4(180 - 10x )
5x = 720 - 40x
45x = 720
x = 16
answer A.
x = 16

The solution to the system of equation is (-4 , 2) , Option A is the right answer.
<h3>What are System Of equation ?</h3>
A set of equation whose factors are common are called system of equations.
It is given in the question
3x +5y = -2
3x +7y = 2
On solving this we get
-2y = -4
y = 2
On substitution in any equation
x = -4
Therefore solution to the system of equation is (-4 , 2) , Option A is the right answer.
