heya friend!!☺☺
here's your 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
hence 11 is the number!!☺
hope it helps you!!☺☺

Number = k
60-4k=7k-61
60+61=7k+4k
121=11k
k=121/11
K=11
60-4k=7k-61
60+61=7k+4k
121=11k
k=121/11
K=11
