Expert verified

The solution of the equation $5 - 2 a = 7$ is $a = - 1$ .

Step by step solution

Step 1. Given information.

The given sentence is:

Five minus the product of 2 and a number is 7.

Step 2. Write the equation.

Consider the number which is the product of 2 be a.

so, the equation is $5 - 2 a = 7$ .

Step 3. Solve the equation.

To solve this equation, find the value of a.

Therefore,

$\begin{array}{l} 5 - 2 a = 7 \\ - 2 a = 7 - 5 \\ - 2 a = 2 \\ a = \frac{2}{- 2} \end{array}$

So, $a = - 1$ $\begin{array}{l} 5 - 2 a = 7 \\ - 2 a = 7 - 5 \\ - 2 a = 2 \\ a = \frac{2}{- 2} \end{array}$
