To solve for x, we can start by simplifying the equation:
0.72 = 0.4(x + 1.4)
Next, distribute the 0.4 to the terms inside the parentheses:
0.72 = 0.4x + 0.56
Subtract 0.56 from both sides to isolate the term with x:
0.72 - 0.56 = 0.4x
0.16 = 0.4x
To solve for x, divide both sides by 0.4:
0.16/0.4 = x
0.4 = x
Therefore, x = 0.4.
