Question

solve the following pair of linear equation graphically 3 X + 2 y = - 4; 3 X - 2y=-8

Answer 1

Here's your answer ,

You can solve this by the method of elimination : 3x+2y= -4
3x-2y= -8
_________
6x = -12
x = -12/6
x = -2

put this in eq. 1

3(-2)+2y = -4
-6 +2y = -4
2y = -4 +6
y = +2/2
y = 1

your answer is →
x = -2
y = 1

Hope, this is helpful to you
