Answer:
Step-by-step explanation:
4x + 3y = -12 -----------------(I)
2x - 3y = 30 ----------------(II)
Add the equations. So, y will be eliminated and we can find the value of x
4x + 3y = -12
<u>2x - 3y = 30 </u>
6x = 18
x = 18/6
x = 3
Plug in the value of x in equation (I)
4*3 + 3y = -12
12 + 3y = -12
3y = -12 - 12
3y = -24
y = -24/3
y = -8
