Question

I need help for this problem!​

Answer 1

`a = 2.7`

Explanation:

Distributive property can be used to solve the equation, by multiplying
`(2)/(3)` with
`6a,` and
`9`

Thus,

`((2)/(3)*6a) + ((2)/(3)*9) = 16.8`

`2*2a + 2*3 = 16.8`

`4a + 6 = 16.8`

Subtract 6 from both sides.

`4a + 6 - 6 = 16.8 - 6`

`4a = 10.8`

Divide both sides by 4 to solve for a

`(4a)/(4) = (10.8)/(4)`

`a = 2.7`
