2+\left(u+7\right)\left(-5\right)=1
Variable u cannot be equal to -7 since division by zero is not defined. Multiply both sides of the equation by u+7.
2-5u-35=1
Use the distributive property to multiply u+7 by -5.
-33-5u=1
Subtract 35 from 2 to get -33.
-5u=1+33
Add 33 to both sides.
-5u=34
Add 1 and 33 to get 34.
u=\frac{34}{-5}
Divide both sides by -5.
u=-\frac{34}{5}
Fraction \frac{34}{-5} can be rewritten as -\frac{34}{5} by extracting the negative sign.
