Question

seventh grade t.10 solve two - step equations solve for u. 39 = \frac{u}{5}+35

Explanation:

Step1: Subtract 35 from both sides

To isolate the term with \( u \), we subtract 35 from both sides of the equation \( 39=\frac{u}{5}+35 \).
\( 39 - 35=\frac{u}{5}+35 - 35 \)
Simplifying both sides, we get \( 4=\frac{u}{5} \).

Step2: Multiply both sides by 5

To solve for \( u \), we multiply both sides of the equation \( 4=\frac{u}{5} \) by 5.
\( 4\times5=\frac{u}{5}\times5 \)
Simplifying both sides, we get \( u = 20 \).

Answer:

\( u = 20 \)
