Step-by-step explanation:
EQUATION 1) 2x - 3y = -4
EQUATION 2) 7x + 9y =- 5
Multiply the whole first equation by 3 so that we could find the values of X first.
1) 3(2x - 3y = -4)
1) 6x-9y=-12
2) 7x+9y=-5
Add the 2 equations together.
13x=-17
x=-17/3 OR -5 2/3
2x-3y=-4
Plug the value of X into the equation.
2(-17/3) -3y=-4
-11 1/3 - 3y=-4
-3y=-4+11 1/3
-3y=22/3
y=-22/9 OR -2 4/9
