Answer:

(18-7x) +1 = -9

Step-by-step explanation:

the difference between 18 and seven times a number. First seven times a number is equal to 7x. Difference means subtract, so you get 18-7x. Now one increased is +1. But we have to put 18-7x into parentheses because if we dont, 18-7x+1, simplifes into 19-7x
