Enter the y coordinate of the solution to this system of equations. <br> -2x+3y=-6<br> 5x-6y=15
julia-pushkina [17]
Y coordinate on solving both equations comes out to be 0
-2x+3y=-6
3y = -6+2x
put the value of 3y in equation 2nd
5x-2(-6+2x) =15
5x+12-4x = 15
x=3
put value of X in 3y = -6+2x
3y = -6+2*3 = -6+6 = 0
thus y = 0
