Question

Four times a certain number is as much less than 120 as seven times the number is greater than 102. Find the number​

Answer 1

Answer:

"4 times a certain number" is rewritten algebraically as 4x

"is as much less than 60" is rewritten that 60 - 4x

"7 times the number" is rewritten as 7x

"is greater than 61" is rewritten as 7x-61

Since the two terms are the same (the second "as"), the two terms can be set equal to one another:

60 - 4x = 7x -61

121 = 11x

x = 11 {Answer}
