I'm doing elemination method
going to eliminate x
change symbols of 2nd EQUATIONS like this
3x + 4y = 10
-3x + 2y = -2
___________
6y = -8
y = -8 / 6
y = -4/3
____________
substitute the value of y in any equation to get x
3x + 4 × -4/3 = 10 -----> equation 1
3x + 4×3 - 4×1 / 3 = 10
3x + 12 - 4 / 3 = 10
3x + 8 / 3 = 10
3x + 8 = 10×3
3x + 8 = 30
3x = 30 - 8
3x = 22
x = 22 / 3
