One-half of a number plus 10 is equal to one-third of the number plus 11.

Question

I need help in turning this into an equation.

Answer 1

(1/2) X + 10 = (1/3) X + 11

multiplies by LCD of 6:

3x + 60 = 2x + 66

Subtracts 2x

x + 60 = 66

Subtracts 60:

x = 6

(1/2)(6) + 10 = 3+10 = 13

(1/3)(6) + 11 = 2 + 11 = 13

yes it checks

6
