What is the solution to 0.4x - 4 < 2.4?

Mathematics
1 answer:
Blizzard [7]3 years ago
5 0

Answer:

x=16

Step-by-step explanation:

Simplifying

0.4x + -4 = 2.4

Reorder the terms:

-4 + 0.4x = 2.4

Solving

-4 + 0.4x = 2.4

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '4' to each side of the equation.

-4 + 4 + 0.4x = 2.4 + 4

Combine like terms: -4 + 4 = 0

0 + 0.4x = 2.4 + 4

0.4x = 2.4 + 4

Combine like terms: 2.4 + 4 = 6.4

0.4x = 6.4

Divide each side by '0.4'.

x = 16

Simplifying

x = 16

Lesechka [4]

EXPLANATION:

-To formulate an equation, you must first know what data the exercise gives us to locate them correctly.

data:

-6 that must be added to a number.

-four times a number that is equal to 4x

-a result that is equal to 50

Now with these data we formulate the equation:

\begin{gathered} \text{Equation:} \\ 6+4x=50;\text{  } \end{gathered}

if we solve the equation we have:

\begin{gathered} 6\text{ }+4x=50 \\ 4x=50-6 \\ 4x=44 \\ x=\frac{44}{4} \\ x=-\frac{22}{2} \\ x=\text{ }-11 \end{gathered}
