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
Step-by-step explanation:
I think i did it correct
4/7=N/12 cross multiply
7N=4*12
7N=48
N=48/7
