Question

Solve system of equations y=3/4x+2 5x+4y=-24

Answer 1

Answer:

$\left \{ {{y=-1} \atop {x=-4}} \right.$

Step-by-step explanation:

$\left \{ {{y=\frac{3}{4} x+2} \atop {5x+4y=-24}} \right. \left \{ {{y=\frac{3}{4}x+2 } \atop {5x+4*(\frac{3}{4}x+2)=-24 }} \right. \left \{ {{y=\frac{3}{4}x+2 } \atop {5x+3x+8=-24}} \right. \left \{ {{y=\frac{3}{4}x+2 } \atop {8x=-32}} \right. \\\left \{ {{y=\frac{3}{4}x+2 } \atop {x=-4}} \right. \left \{ {{y=\frac{3}{4}*(-4)+2 } \atop {x=-4}} \right. \left \{ {{y=-3+2} \atop {x=-4}} \right. =>\left \{ {{y=-1} \atop {x=-4}} \right.$
