$\cfrac{7-4i}{2+i}\\\\ = \cfrac{(7-4i)(2-i)}{(2+i)(2-i)} \\\\ =\cfrac{14-7i-8i-4}{4+1} \\\\= \cfrac{10-15i}{5} \\\\= \cfrac{5(2-3i)}{5} \\\\=2-3i$

Answer:

0=1/3x−2

Rewrite the equation as 1/3x−2=0.

1/3x−2=0 Combine 13 and x.

x/3−2=0

Add 2 to both sides of the equation.

x/3=2 Multiply both sides of the equation by 3.

3⋅x/3=3⋅2

Simplify both sides of the equation.

x=6
