Question

Solve the following system: 5x + 4y = 6 -2x – 3y = -1​

Answer 1

Answer:

$\left \{ {{y=-1} \atop {x=2}} \right.$

Step-by-step explanation:

$\left \{ {{5x+4y=6} \atop {-2x-3y=-1}} \right. \left \{ {{10x+8y=12} \atop {-10x-15y=-5}} \right. \left \{ {{-7y=7} \atop {-10x-15y=-5}} \right. \left \{ {{y=-1} \atop {-10x-15y=-5}} \right. \left \{ {{y=-1} \atop {-10x+15=-5}} \right. \left \{ {{y=-1} \atop {-10x=-20}} \right. => \left \{ {{y=-1} \atop {x=2}} \right.$
