5\times 7=6\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 5\left(u+2\right), the least common multiple of u+2,5.
35=6\left(u+2\right)
Multiply 5 and 7 to get 35.
35=6u+12
Use the distributive property to multiply 6 by u+2.
6u+12=35
Swap sides so that all variable terms are on the left hand side.
6u=35-12
Subtract 12 from both sides.
6u=23
Subtract 12 from 35 to get 23.
u=\frac{23}{6}
Divide both sides by 6.
