Solve for x. 0.72=0.4(x+1.4) (1 point) Responses

Question

x = -1.4
x = 0.27
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 the 0.4 to both terms inside the parentheses:

0.72 = 0.4x + 0.4(1.4)

Next, simplify:

0.72 = 0.4x + 0.56

Now, subtract 0.56 from both sides of the equation:

0.72 - 0.56 = 0.4x + 0.56 - 0.56

0.16 = 0.4x

Finally, divide both sides of the equation by 0.4:

0.16/0.4 = 0.4x/0.4

0.4 = x

Therefore, the solution is x = 0.4.
