x = -1.4
x = -1.4

x = 0.27
x = 0.27

x = 1.2
x = 1.2

x = 0.4

Answer 1

To solve for x, we need to isolate it on one side of the equation.

0.72 = 0.4(x + 1.4)

First, distribute 0.4 to both terms inside the parentheses:

0.72 = 0.4x + 0.56

Now, we can subtract 0.56 from both sides to isolate 0.4x:

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

x = 0.4

Therefore, x = 0.4.
