I need help for this problem!​

Answer 1

Answer:

$a = 2.7$

Step-by-step explanation:

Distributive property can be used to solve the equation, by multiplying $\frac{2}{3}$ with $6a,$ and $9$

Thus,

$(\frac{2}{3}*6a) + (\frac{2}{3}*9) = 16.8$

$2*2a + 2*3 = 16.8$

$4a + 6 = 16.8$

Subtract 6 from both sides.

$4a + 6 - 6 = 16.8 - 6$

$4a = 10.8$

Divide both sides by 4 to solve for a

$\frac{4a}{4} = \frac{10.8}{4}$

$a = 2.7$
