7/3

Step-by-step explanation:

4 - 7 = 3k - 3-7

=> -3 + 10 = 3k

=> 7 = 3k

=> 7/3 = k

=> k = 7/3

Answer:

7/3 =k

Step-by-step explanation:

4. -7 = 3k - 3-7

Combine like terms

-3 = 3k-10

Add 10 to each side

-3+10 = 3k-10+10

7 = 3k

Divide each side by 3

7/3 = 3k/3

7/3 =k

$\bf \begin{array}{ccll} tons&weeks\\ \cline{1-2}\\ \frac{3}{4}&1\frac{1}{2}\\\\ 2&x \end{array}\implies \cfrac{~~\frac{3}{4}~~}{2}=\cfrac{~~1\frac{1}{2}~~}{x}\implies \cfrac{~~\frac{3}{4}~~}{2}=\cfrac{~~\frac{3}{2}~~}{x}\implies \cfrac{~~\frac{3}{4}~~}{\frac{2}{1}}=\cfrac{~~\frac{3}{2}~~}{\frac{x}{1}} \\\\\\ \cfrac{3}{4}\cdot \cfrac{1}{2}=\cfrac{3}{2}\cdot \cfrac{1}{x}\implies \cfrac{3}{8}=\cfrac{3}{2x}\implies 6x=24\implies x=\cfrac{24}{6}\implies x=4$
