Six less than seven times a number is equal to negative twenty.

Let x = your number

7x - 6 = -22.

Add 6 to each side

7x = -16.

Divide each side by 7

x = - 16/7

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.

answer is c
