What is the first step in solving for X in the equation 5.6 (X + 1.42) =7.8

Answer 1

The first step in solving for X in the equation 5.6 (X + 1.42) =7.8 is to distribute the 5.6 to the terms inside the parentheses.

This can be done by multiplying 5.6 with both X and 1.42:

5.6(X + 1.42) = 7.8

5.6 * X + 5.6 * 1.42 = 7.8

Now, the equation becomes:

5.6X + 7.952 = 7.8
