We want to solve the following equation


\text{ -9=}(e)/(3)+6

for the variable e. To do, we should apply mathematical operations on both sides of the equation, so we isolate the variable on one side of the equation. First we begin by removing the 6. To do so, we should subtract 6 on both sides, so we get


(e)/(3)=\text{ -9-6 = -15}

Now, the only factor we are missing is the 3, that is dividing the variable. So, to remove this factor, we should multiply by 3 on both sides. So we get


e=3\cdot(\text{ -15)= -45}

So the value we get is -45. Now, we should check this value. To do so, we will take the expression that has the variable and replace the value we found. We get


(e)/(3)+6=\text{ -45/3+6 = -15+6= -9}

So, since we got the value that is on the other side of the equation, we confirm that e=-45 is the correct value
