<human>:  Sara and Joe have a combined height of 120 inches. Joe is 6 inches more than double Sara's height. How tall is Joe?
<bot>: Define a variable ** Let x be Sara's height in inches
How tall is Joe? ** Joe is 6+2x inches tall
Set up an equation ** 120=x+(6+2x)
Combine like terms ** 120=3x+6
Subtract 6 from both sides ** 114=3x
Divide by 3 ** x=<<38=38>>38 inches
How tall is Joe? ** Joe is 6+2(38)=82 inches
#### 82
