Question

Solve the following equation
3-n = 3
________ __
2 4

Answer 1

3/2

Answer 2

Multiply both sides by 4.

\( \color{Black}{\Rightarrow \Large {4(3- n) \over 2} = 3}\)

Multiply both sides by 2.

\( \color{Black}{\Rightarrow \Large {4(3 - n) = 6}}\)

\( \color{Black}{\Rightarrow 12 - 4n = 6}\)

\( \color{Black}{\Rightarrow -4n = -6}\)

\( \color{Black}{\Rightarrow 4n = 6}\)

\( \color{Black}{\Rightarrow n = 6 \div 4 = 1.5}\)

Answer 3

Cross Multiply:

4(3 - n) = 3*2
12 - 4n = 6

4n = 12 - 6

n = 6/4 = 3/2..
