Question 1199270
<br>
2x + 3y = -16
5x - 10y = 30<br>
Simplify the second equation and solve for x:<br>
x - 2y = 6
x = 2y + 6<br>
Substitute for x in the first equation and solve for y:<br>
2(2y + 6) + 3y = -16
4y + 12 + 3y = -16
7y = -28
y = -4<br>
Substitute in either original equation and solve for x:<br>
2x + 3(-4) = -16
2x - 12 = -16
2x = -4
x = -2<br>
ANSWERS: x = -2; y = -4<br>
You should of course check your answers in the original equations; I won't take the time to so that here.<br>
