Question

Which shows the correct solution of the equation, when 1/2a+2/3b=50, when b=50 ?

Answer 1

Answer a=60 (3rd option)

Explanation:

Answer 2

`a = (100)/(3)`

Explanation:

We have the following equation:

`(1)/(2) a + (2)/(3) b = 50`

If
`b=50`, then:

`(1)/(2) a + (2)/(3)`×50
`= 50`

Solving for 'a':

`(1)/(2) a = (50)/(3)`

`(1)/(2) a = (50)/(3)`

`a = 2(50)/(3)`

`a = (100)/(3)`
