p+2i=13\left(1-2i\right)
Multiply both sides by 1-2i.
p+2i=13\times 1+13\times \left(-2i\right)
Multiply 13 times 1-2i.
p+2i=13-26i
Do the multiplications in 13\times 1+13\times \left(-2i\right).
p=13-26i-2i
Subtract 2i from both sides.
p=13+\left(-26-2\right)i
Combine the real and imaginary parts in numbers 13-26i and -2i.
p=13-28i
Add -26 to -2.
