Zorluk: KolaySolving One-Variable Linear Equations

If $4(k - 3) = 28$ , what is the value of $k$ ?

Cevap: 10

Applying inverse operations to isolate the variable results in

k = 10

. This can be verified by substituting 10 back into the original equation:

4(10 - 3) = 4(7) = 28

, which makes the statement true.

Divide both sides by 4.

k - 3 = 7

Dividing by the coefficient outside the parentheses simplifies the equation and isolates the binomial.

Add 3 to both sides of the equation.

k = 10

Using the inverse operation of subtraction isolates the variable
