Question

Three times the sum of half a number and 7 is 36

Answer 1

your answer is 19.34

Explanation:

let the number be x

half a number = ½ x

three times means multiplied by three

so,

3( ½ x) + 7 = 36

3( ½ x) = 36 - 7

3( ½ x) = 29

½ x = 29/3

½ x = 9.67...

x = 9.67 × 2 (when we moved ½ on the other side of the equal sign it › turns into 2/1 )

x = 19.34
