1/2x-3=7
(Show all work)

X= 5

Step-by-step explanation:

1/2x -3 = 7

first you + 3 to both sides to get the x by it's self on one side of the (=)

Why +3 and not -3? because if you add 3 to the -3 on that side it goes to 0 witch means there is nothing there!

1/2x= 10

now you (/) by 2

10/2 =5

x=5

x=20

Step-by-step explanation:

1/2x-3=7

add 3 to both sides

1/2x=10

divide both sides by 1/2

10/.5= 20

x=20

step-by-step explanation:

one day the were 5 ducks, and their king told them to multiply their kingdom. so each went their own seperate way and met 4 other ducks on their journey.

when the ducks returned to their kingdom, it was discovered that there were 5 groups of 5 ducks. when the kind counted the number of ducks in total (including the ones he sent out earlier) he counted 25.

therefore 5 times 5 is 25.

the end. : )
