5a-5=7+2a -- we need to isolate a. Subtract 2a from both sides

3a-5=7 -- add 5 to both sides
3a=12 -- divide by 3

a=4

yanalaym [24]

Answer:

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

Step-by-step explanation:

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