How do I solve 3+k/14=4
Sedaia [141]

Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{k = 53}}}}}

Step-by-step explanation:

\bigstar{ \sf{   \:  \: \frac{3 + k}{14} = 4}}

\tt{Step \: 1 \: } : Do cross multiplication

\hookrightarrow{ \sf{3 + k = 4 \times 14}}

\tt{Step \: 2} : Multiply the numbers : 4 and 14

\hookrightarrow{ \sf{3 + k = 56}}

\tt{Step \: 3 \: } Move 3 to right hand side and change it's sign

\hookrightarrow{ \sf{k = 56 - 3}}

\tt{Step \: 4 \: } Subtract 3 from 56

\hookrightarrow{ \sf{k = 53}}

The value of k is 53

Hope I helped!

Best regards! :D
