Answer 2

is your problem : -7/5(u) - 3/5 = 7u - 1/2 ??
OR
-7/(5u) - 3/5 = 7u - 1/2

Answer 3

let me use the equation option...one second

Answer 4

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

Answer 5

It looks like that!

Answer 6

-7/5u - 3/5 = 7u - 1/2 --- multiply entire equation by the LCD, which is 10
-14u - 6 = 70u - 5 -- subtract 70u from both sides
-14u - 70u - 6 = -5 -- add 6 to both sides
-14u - 70u = -5 + 6 -- combine like terms
-84u = 1 -- divide by -84
u = - 1/84

any questions ?
