Answer :

The solution to the given system of equation is -3

System of equation

Given the system of equation below;

-4x+3y= = -21

-2x -3y = 3

Add both equation to have;

-4x - 2x = -21 + 3

-6x = -18

x =. 3

Substitute x = 3 into any of the equation to have;

-2(3) - 3y = 3

-6 - 3y = 3

-3y = 3 + 6

-3y = 9

y = -3

Hence the solution to the given system of equation is -3
