Question

What is the solution of the equation 2 1/4+ x= 5 1/4? x= ?

Answer 1

It is required to solve the equation:

`2(1)/(4)+x=5(1)/(4)`

To do this, subtract 2 1/4 from both sides of the equation:

`\begin{gathered} 2(1)/(4)-2(1)/(4)+x=5(1)/(4)-2(1)/(4) \\ \Rightarrow x=5(1)/(4)-2(1)/(4) \end{gathered}`

Subtract the mixed fractions on the right:

`\begin{gathered} x=(5+(1)/(4))-(2+(1)/(4)) \\ \Rightarrow x=5+(1)/(4)-2-(1)/(4) \\ \Rightarrow x=5-2+(1)/(4)-(1)/(4) \\ \Rightarrow x=3+0=3 \end{gathered}`

The answer is x=3.
