What is the value of x in the equation 1/3x − 2/3 =− 18?

Klio2033 [76]

Answer:

x = -52

Step-by-step explanation:

$\frac{1}{3}x-\frac{2}{3}=-18$

Let us solve for x.

$\frac{1}{3}x=-18+\frac{2}{3}$

$\frac{1}{3}x=-\frac{18*3}{1*3} +\frac{2}{3}$

$\frac{1}{3}x=-\frac{54}{3} +\frac{2}{3}$

$\frac{1}{3}x=\frac{-54+2}{3}$

$\frac{1}{3}x=\frac{-52}{3}$

Use cross multiplication to find the value of x.

$\frac{1x}{3}=\frac{-52}{3}$

$3*1x=3*-52$

$3x=-156$

Divide both sides by 3.

x = - 52
