(7 - 3)/(9 - 2) = 4/7
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.
