We will have:


8i+5-2i=3i+23

We will operate like terms and solve for i, that is:


8i-2i-3i=23-5\Rightarrow3i=18\Rightarrow i=6

*Step by step:


8i+5-2i=3i+23\Rightarrow6i+5=3i+23
\Rightarrow6i+5-5=3i+23-5\Rightarrow6i=3i+18
\Rightarrow6i-3i=3i+18-3i\Rightarrow3i=18
\Rightarrow(3)/(3)i=(18)/(3)\Rightarrow i=6
