# How do you solve 8.9+1.2(3a-1)=14.9?

Mar 7, 2018

$a = 2$

#### Explanation:

$8.9 + 1.2 \left(3 a - 1\right) = 14.9$

Start by subtracting $8.9$ from both sides

$1.2 \left(3 a - 1\right) = 6$

Then divide both sides by $1.2$

$3 a - 1 = 5$

Now add $1$ to both sides

$3 a = 6$

And finally, divide both sides by $3$

$a = 2$
