Question

Part A :Han's age increased by 21 is 64.Use the variable h to represent Han's age.Part B : The difference of Han's age and 17 is 54

Answer 1

Let the age of Han = h

Part A : Given : Han's age increased by 21 is 64.

So, the equation that represent the Han's age will be :

$h+21=64$

Solve for h :

$\begin{gathered} h+21=64 \\ h=64-21 \\ \\ h=43 \end{gathered}$

Part B : If The difference of Han's age and 17 is 54​

So, the equation will be :

$h-17=54$

in this case h will be : h = 54 + 17 = 71
