42.172-5•x=7152

To solve the equation \( 42.172 - 5 \cdot x = 7152 \), follow these steps:

1. Start by isolating the term with \( x \). Subtract \( 42.172 \) from both sides of the equation:

\[ -5 \cdot x = 7152 - 42.172 \]

2. Perform the subtraction on the right side:

\[ 7152 - 42.172 = 7110.828 \]

So now the equation is:

\[ -5 \cdot x = 7110.828 \]

3. Next, divide both sides by \( -5 \) to solve for \( x \):

\[ x = \frac{7110.828}{-5} \]

4. Calculate the division:

\[ x = -1422.1656 \]

Therefore, the solution is:

\[ x \approx -1422.17 \] (rounded to two decimal places)
