1. The difference between three times a number and 11 is 10.
Whould it be: 3x - 11 = 10?
2. One more than the difference between 18 and seven times a number is -9.
Would it be: 1 + 18 - 7x = -9?
3. 26 more than the product of a number and 17 is -42.
Would it be: 26 + x + 17 = -42?
4. Twelve less than the quotient of a number and 8 is -1.
Would it be: 12 - x/8 = -1?
1. Correct.
2.
(18 - 7x) + 1 = -9
3.
17x + 26 = -42
4. Incorrect.
Please try again
4. 12 - a + 8 = 1?
4. Quotients are the answers to a division problem. Your first answer was on the right track, except that it didn't show 12 less than the quotient.
12 + x/8 = -1
Since you'll later turn the + into a -
OR
x/8 - 12 = -1?
This is correct:
x/8 - 12 = -1
Now how would you go by solving, x/8 - 12 = -1?
x/8 - 12 = -1
Multiply both sides of the equation by 8.
x - 96 = -8
x = 96 - 8
x = 88
Proof:
(88/8) - 12 = -1
11 - 12 = -1
