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 can start by simplifying the equation.

0.72 = 0.4(x + 1.4)

Distribute the 0.4:

0.72 = 0.4x + 0.56

Subtract 0.56 from both sides:

0.72 - 0.56 = 0.4x

0.16 = 0.4x

Now divide both sides by 0.4:

0.16/0.4 = x

0.4 is the same as 4/10, so:

0.16/(4/10) = x

Multiply the numerator and denominator of the fraction by 10:

0.16*10/(4*10) = x

1.6/4 = x

Simplify the fraction:

0.4 = x

So the solution is x = 0.4.
