5i+2j-8k=B
Swap sides so that all variable terms are on the left hand side.
2j-8k=B-5i
Subtract 5i from both sides.
2j=B-5i+8k
Add 8k to both sides.
2j=B+8k-5i
The equation is in standard form.
\frac{2j}{2}=\frac{B+8k-5i}{2}
Divide both sides by 2.
j=\frac{B+8k-5i}{2}
Dividing by 2 undoes the multiplication by 2.
j=\frac{B}{2}+4k-\frac{5}{2}i
Divide B-5i+8k by 2.
