2e+4j-3k=p
Swap sides so that all variable terms are on the left hand side.
4j-3k=p-2e
Subtract 2e from both sides.
4j=p-2e+3k
Add 3k to both sides.
4j=p+3k-2e
The equation is in standard form.
\frac{4j}{4}=\frac{p+3k-2e}{4}
Divide both sides by 4.
j=\frac{p+3k-2e}{4}
Dividing by 4 undoes the multiplication by 4.
j=\frac{p}{4}+\frac{3k}{4}-\frac{e}{2}
Divide p-2e+3k by 4.
2e+4j-3k=p
Swap sides so that all variable terms are on the left hand side.
4j-3k=p-2e
Subtract 2e from both sides.
-3k=p-2e-4j
Subtract 4j from both sides.
-3k=p-4j-2e
The equation is in standard form.
\frac{-3k}{-3}=\frac{p-4j-2e}{-3}
Divide both sides by -3.
k=\frac{p-4j-2e}{-3}
Dividing by -3 undoes the multiplication by -3.
k=\frac{2e+4j-p}{3}
Divide p-2e-4j by -3.
