Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : X= 49

Answer: x = 49 . _____________________________________________________ 13-x/7=6 ; is: 13 - (x/7) = 6 ; So, 13 - y = 6 ; solve for "y"; y = 7; so; (x/7) = y = 7 ; (x/7) = 7; 7 * 7 = x ; x = 49 . ____________________________________________________
