ПОМОГИТЕ ПОЖАЛУЙСТА ОЧЕНЬ СРОЧНО Решить систему уравнений {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
