Question

find the value please give correct answer ​

Answer 1

Step-by-step explanation:

1) Given equation is 5y²+6y-a=8

If y=2 then,

=>5(2)²+6(2)-a=8

=>5(4)+6(2)-a=8

=>20+12-a=8

=>32-a=8

=>32-8=a

=>24=a

=>a=24

The value of a =24

2)Given equation is 6m²-5mn+2b=-10

If m=1 and n=-2 then,

=>6(1)²-5(1)(-2)+2b=-10

=>6(1)-5(-2)+2b=-10

=>6+10+2b=-10

=>16+2b=-10

=>2b=-10-16

=>2b=-26

=>b=-26/2

=>b=-13

The value of b=-13

Answer 2

Answer:

24 and-13 are the values of a,b respectively
