Gavyn was thinking of a number. Gavyn adds 12 then divides by 6 to get an answer of 20. Form an equation with x
from the information.

What is the solution to the system of the equations? x = y - 3 x + 3y = 13

Which equation and solution can be used to solve this problem? thirteen less than a number is sixteen. 13-n=16: add 13 to both sides. the answer is 29. n+13=16: subtract 13 from both sides. the answer is 3. n+16=13 subtract 13 from both sides. the answer is 3. n-13=16: add 13 to both sides. the answer is 29.
