The sum of two numbers is 87, and one number is eleven more than the other. find the number

use x to represent the unkown numbers

and y to represent the one number which is more than 11

so the equation will be like this

x+x+y=87

x+x+11=87

2x+11=87

2x=87-11

2x=76

now divide both sides by the x variable

2x/2=76/2

x=38

now you know one x to be 38

and the question made it clear that one number is eleven times more than the other

therefore the other number is 49

so 38+49=87
