1-3=4\left(u-2\right)
Variable u cannot be equal to 2 since division by zero is not defined. Multiply both sides of the equation by u-2.
-2=4\left(u-2\right)
Subtract 3 from 1 to get -2.
-2=4u-8
Use the distributive property to multiply 4 by u-2.
4u-8=-2
Swap sides so that all variable terms are on the left hand side.
4u=-2+8
Add 8 to both sides.
4u=6
Add -2 and 8 to get 6.
u=\frac{6}{4}
Divide both sides by 4.
u=\frac{3}{2}
Reduce the fraction \frac{6}{4} to lowest terms by extracting and canceling out 2.
