Question

-19.7 = \frac{u}{7} - 2.2

Explanation:

Step1: Identify the equation

The equation is $-19.7 = \frac{u}{7}-2.2$.

Step2: Add 2.2 to both sides

To isolate the term with $u$, add 2.2 to both sides: $-19.7 + 2.2=\frac{u}{7}-2.2 + 2.2$.
Calculating the left side: $-17.5=\frac{u}{7}$.

Step3: Multiply both sides by 7

Multiply both sides by 7 to solve for $u$: $-17.5\times7=\frac{u}{7}\times7$.
Calculating the left side: $u=-122.5$.

Answer:

$u = -122.5$
