Construct an equation for the expression: the sum of a number and itself is 8. show the solution to the equation and prove your solution to be true through your work.

me i'm so behind on my schooling need the answer asap you

equation : 2x = 8

solution : x = 4

Step-by-step explanation:

let the number be x

"the sum of a number and itself "

= sum of x and x

= x + x

= 2x

"the sum of a number and itself  is 8"

2x = 8

solving the equation, divide both sides by 2

2x = 8

x = 8/2

x = 4

nope.   happens to me as well.
