Solve for. 6u+7u-16=-81

Simplify your answer as much as possible.

-5

Step-by-step explanation:

6u+7u-16=-81

Carry over the "-16" and make "u" the subject.

6u+7u = - 81+16

13u = - 65

Carry over the "13" and make "u" the subject

u = - 65/13

u = - 5

6u+7u-16=-81

We simplify the equation to the form, which is simple to understand

6u+7u-16=-81

We move all terms containing u to the left and all other terms to the right.

+6u+7u=-81+16

We simplify left and right side of the equation.

+13u=-65

We divide both sides of the equation by 13 to get u.

u=-5
