Half a number plus eight is fourteen minus a number

the number is 4

Step-by-step explanation:

let the number be x then half the number is 0.5x, hence the equation is

0.5x + 8 = 14 - x ( add x to both sides )

1.5x + 8 = 14 ( subtract 8 from both sides )

1.5x = 6 ( divide both sides by 1.5 )

x = 4
