what is the step in solving for x in the equation 5.6 (x+1.42) = 7.8?

Answer 1

To solve for x in the equation 5.6(x + 1.42) = 7.8, you would follow these steps:

1. Distribute 5.6 to both terms inside the parentheses:
5.6 * x + 5.6 * 1.42 = 7.8
5.6x + 7.952 = 7.8

2. Subtract 7.952 from both sides of the equation to isolate the term with x:
5.6x + 7.952 - 7.952 = 7.8 - 7.952
5.6x = -0.152

3. Divide both sides of the equation by 5.6 to solve for x:
(5.6x)/5.6 = -0.152/5.6
x = -0.02714

The solution to the equation 5.6(x + 1.42) = 7.8 is x = -0.02714.
