FIND (X)

==============================

» Find the value of (x) on the "if" statement to substitute it to the "then" statement.

[tex] \implies \sf \large \frac{2x}{3} - 70 = 30 \\ [/tex]

[tex]\implies \sf \large \frac{2x}{3} = 30 + 70 \\ [/tex]

[tex]\implies \sf \large \frac{2x}{3} = 100 \\ [/tex]

[tex]\implies \sf \large2x = 100 \cdot3[/tex]

[tex]\implies \sf \large2x = 300[/tex]

[tex]\implies \sf \large x = \frac{300}{2} \\ [/tex]

[tex]\implies \sf \large x = 150[/tex]

» Substitute the value of (x) to the "then" statement to find the missing number. Let (y) be the missing number.

[tex]\implies \sf \large x \cdot \frac{1}{4} = y \\ [/tex]

[tex]\implies \sf \large y = 150 \cdot \frac{1}{4} \\ [/tex]

[tex]\implies \sf \large y = \frac{150}{4} \\ [/tex]

[tex]\implies \sf \large y = 37.5[/tex]

Final Answer:

[tex] \tt \huge» \: \purple{37.5 }[/tex]
