7(x−5)−9=334 what is the answer of x

slega [8]

Answer:

$\boxed {x = 54}$

Step-by-step explanation:

Solve for the value of $x$ :

$7(x - 5) - 9 = 334$

-Use <u>Distributive Property</u>:

$7(x - 5) - 9 = 334$

$7x - 35 - 9 = 334$

-Combine like terms:

$7x - 35 - 9 = 334$

$7x - 44 = 334$

-Add both sides by $44$ :

$7x - 44 + 44 = 334 + 44$

$7x = 378$

-Divide both sides by $7$ :

$\frac{7x}{7}= \frac{378}{7}$

$\boxed {x = 54}$

Therefore, the value of $x$ is $54$ .
