Answer 1

The account A has amount $600 and B has $1600.

Explanation:

The given equations are:

a+b=2200 ⇒1

0.03a+0.05b=98 or
`(3)/(100)a`+
`(5)/(100)b`⇒2

Change the first equation by isolating a,

a = 2200-b. ⇒3

Apply equation 3 in 2,

`(3)/(100)(2200-b)`+
`(5)/(100)b`=98.

66-
`(3)/(100) b`+
`(5)/(100)b`=98.

66+
`(2)/(100) b` = 98.

6600+2b=9800.

2b=9800-6600.

2b=3200.

b=1600.

Substitute b value in equation 3

a=2200-1600.

a=600.
