Answer:
x = - 52
Step-by-step explanation:
Given
[tex]\frac{1}{3}[/tex] x - [tex]\frac{2}{3}[/tex] = - 18 ( multiply through by 3 to clear the fractions )
x - 2 = - 54 ( add 2 to both sides )
x = - 52
[tex]\implies {\blue {\boxed {\boxed {\purple {\sf {b. \:-52}}}}}}[/tex]
[tex]\sf \bf {\boxed {\mathbb {STEP-BY-STEP\:\:EXPLANATION:}}}[/tex]
[tex] \frac{1}{3} x - \frac{2}{3} = - 18\\[/tex]
➺[tex] \: \frac{1}{3} x = - 18 + \frac{2}{3}\\ [/tex]
➺[tex] \: \frac{1}{3} x = \frac{ - 18 \times 3}{1 \times 3} + \frac{2}{ 3} \\[/tex]
➺[tex] \: \frac{1}{3} x = \frac{ - 54 + 2}{3}\\ [/tex]
➺[tex] \: \frac{1}{3} x = \frac{ - 52}{3} \\[/tex]
➺[tex] \: x = \frac{ - 52 \times 3}{3}\\ [/tex]
➺[tex] \: x = - 52\\[/tex]
[tex]\sf\pink{Therefore, \:the \:value \:of\: x\:is \:-52.}[/tex]
[tex]\sf \bf {\boxed {\mathbb {TO\:VERIFY:}}}[/tex]
[tex] \frac{1}{3} \times ( - 52) - \frac{2}{3} = - 18\\[/tex]
➼[tex] \: \frac{ - 52}{3} - \frac{2}{3} = - 18\\[/tex]
➼[tex] \: \frac{ - 52 - 2}{3} = - 18\\[/tex]
➼[tex] \: \frac{ - 54}{3} = - 18\\[/tex]
➼[tex] \: - 18 = - 18\\[/tex]
➼ L. H. S. = R. H. S.
Hence verified.
