Answer:
Step-by-step explanation:
Five students= 5x
They all got two more= 5x + 2(5)
5x + 10 = 30
<u> - 10 -10</u>
<u>5x = 20</u>
5
x = 4
We can put this word problem into an equation.
1/3x = 7
Now we just have to solve for x. To find x we need to multiply by three on both sides.
1/3x = 7
*3 *3
-------------
x = 21
So it will take 21 hours to paint one wall.
