Question

solve for u,-u - 1/2 =7/5u - 3/5u=?

Answer 1

We are given the following expression:

$-u-\frac{1}{2}=\frac{7}{5}u-\frac{3}{5}$

We are asked to solve for "u". To do that we will first subtract 7u/5 on both sides:

$-u-\frac{7}{5}u-\frac{1}{2}=\frac{7}{5}u-\frac{3}{5}-\frac{7}{5}u$

Solving the operations:

$-\frac{12}{5}u-\frac{1}{2}=-\frac{3}{5}$

Now we add 1/2 on both sides:

$-\frac{12}{5}u-\frac{1}{2}+\frac{1}{2}=-\frac{3}{5}+\frac{1}{2}$

Solving the operations:

$-\frac{12}{5}u=-\frac{1}{10}$

Now we multiply both sides by 5

$-12u=-\frac{1}{10}(5)$

Simplifying the fraction to the right:

$-12u=-\frac{1}{2}$

Now we divide by -12

$u=(-\frac{1}{12})(-\frac{1}{2})$

Solving the operations we get:

$u=\frac{1}{24}$

Therefore the result of solving for "u" is: u = 1/24
