# How do you solve and check your solutions to 1.2j-4.3=1.7?

Aug 5, 2016

Add $4.3$ to each side and divide each side by $1.2$. To check you solution, substitute your answer for $j$.

#### Explanation:

First, let's add 4.3 to each side:

$1.2 j - 4.3 + 4.3 = 1.7 + 4.3$

$1.2 j = 6$

Next, divide each side by $1.2$:

$\frac{1.2 j}{1.2} = \frac{6}{1.2}$

$j = 5$

To check your answer, substitute $5$ for $j$:

$1.2 \left(5\right) - 4.3 = 1.7$

$6 - 4.3 = 1.7$

$1.7 = 1.7$

Our answer is $5$.
