6x-2-5x=5-\left(3x+i\right)
Use the distributive property to multiply 2 by 3x-1.
x-2=5-\left(3x+i\right)
Combine 6x and -5x to get x.
x-2=5-3x-i
To find the opposite of 3x+i, find the opposite of each term.
x-2+3x=5-i
Add 3x to both sides.
4x-2=5-i
Combine x and 3x to get 4x.
4x=5-i+2
Add 2 to both sides.
4x=5+2-i
Combine the real and imaginary parts in numbers 5-i and 2.
4x=7-i
Add 5 to 2.
x=\frac{7-i}{4}
Divide both sides by 4.
x=\frac{7}{4}-\frac{1}{4}i
Divide 7-i by 4 to get \frac{7}{4}-\frac{1}{4}i.
