Question

Solve for u.- 7 = 4u +5(u-5)Simplify your answer as much as possible.

Answer 1

u = 2

Explanation:

We have the following equation:

`-\: 7\: =\: 4u\: +5\mleft(u-5\mright)`

We solve for u:

`\begin{gathered} 4u\: +5\mleft(u-5\mright)=-7 \\ 4u+5u-25=-7 \\ 9u=-7+25 \\ u=(18)/(9) \\ u=2 \end{gathered}`

The solution of the equation is 2
