Question

the difference of two numbers is 7 . six times smaller plus larger is 77. find the numbers

Answer 1

let the no. be a and b, a>b
a+b=7
therefore,a=7-b
a+6b=77
7-b+6b=77
5b=77-7
b=70/5
b=14
a= -7

Answer 2

let be bigger x and smaller x-7
6(x-7)+x=77
6x-42+x=77
7x-42=77
7x=77+42=119
x=119/7
x=17
x-7=10
