4x - 3y = 8 ⇒ 8x - 6y = 16 
5x - 2y = -11 ⇒ 15x - 6y = -33
 -7x = 49 
 -7 -7
 x = -7
 4x - 3y = 8
 4(-7) - 3y = 8 
 -28 - 3y = 8
 + 28 + 28
 -3y = 36
 -3 -3
 y = -12
 (x, y) = (-7, -12)
To use elimination you have to multiply the first graph by 2 and the second graph by 3 so that the two y-axis can be equal to -6. Then you do the rest to find the answer of the x-axis and the y-axis.
