Question

Half a number increased by 4 is the same as six less than that number

Answer 1

the number is 20

Explanation:

Denote the number as "x",

write out the problem:

(1/2(x)) + 4 = x - 6

inverse operations

(1/2(x)) + 4 = x - 6

+6 +6

(1/2(x)) + 10 = x

-(1/2(x)) -(1/2(x))

10 = ((1/2)x)

*2 *2

20 = x
