Question 268972
(9((x+9)/(7))-7)

Multiply 9 by each term inside the parentheses.
(9(x+9))/(7)-7

Multiply each term by a factor of 1 that will equate all the denominators.  In this case, all terms need a denominator of 7.
(9(x+9))/(7)-7*(7)/(7)

Multiply the expression by a factor of 1 to create the least common denominator (LCD) of 7.
(9(x+9))/(7)-(7*7)/(7)

Multiply 7 by 7 to get 49.
(9(x+9))/(7)-(49)/(7)

The numerators of expressions that have equal denominators can be combined.  In this case, (9(x+9))/(7) and -((49))/(7) have the same denominator of 7, so the numerators can be combined.
(9(x+9)-(49))/(7)

Simplify the numerator of the expression.
Answer: (9x+32)/(7)
