How do I solve this step by step
using linear combination method
2x-3y=13
x+2y=-4
2x-3y=13
x+2y=-4 Multiply THIS equation by -2
-2x-4y=8 add this to TOP equation
-7y = 21
y = -3 now substitue this 'y' value back into one of the equations to find the 'x' value of the coordinate
You can pick either of the equations....just put in -3 where 'y' is to find x
x + 2(-3) = -4
