Question

Seven less than two times a number is 29.
 
Enter the equation that represents Sharon's sentence into the box.
Use x for the variable.

Answer 1

2x-7=29

"Seven less than" => minus 7.
"Two times a number" => 2x (x is the unknown number)
"is twenty-nine" => =29
Putting it all together, 

-7 + 2x = 29
or
2x-7=29
(if you were wondering x is equal to 18)
