{5x+y=24
{2x+3y=33

Answer 1

$left { {{5x+y=24} atop {2x+3y=33}} right. left { {{y=-5x+24} atop {2x+3y=33}} right. left { {{y=-5x+24} atop {2x+3(-5x+24)=33}} right. left { {{y=-5x+24} atop {-13x+39=0}} right. left { {{y=-5x+24} atop {x=3}} right. left { {{y=9} atop {x=3}} right.$

Answer 2

y = 24 - 5x
2x + 3( 24 - 5x ) = 33
2x + 72 - 15x = 33
- 13x = - 39
X = 3
y = 24 - 15 = 9
