Question 504393
Read carefully and set up an equation.
sum of 6 and twice a number= 6+2x
7 less than a number       = x-7

Since these two are said to be equal,
set them equal to each other and solve for x
--------------------------------------
6+2x=x-7   (subtract x from each side)
6+x=-7     (subtract 6 from each side)
x=-13
-------------- ----------------------

Now that we have the value of x,
replace x in the original equation and solve.\
6+2x=x-7
6+2(-13)=-13-7
6-26   =-20
-20=-20  CHECK!
-------------------------------
answer=-20
