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

First, let's add 4.3 to each side:

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

$1.2j=6$

Next, divide each side by $1.2$ :

$(1.2j)/1.2=6/1.2$

$j=5$

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

$1.2(5)-4.3=1.7$

$6-4.3=1.7$

$1.7=1.7$

Our answer is $5$ .
