When a number is increased by 3 and that number is doubled, the result is -8. What was the original number?

The original number is -7.

Step-by-step explanation:

In this section, we are trying to figure out a mysterious number. Let's call this number y. To find the value of y, we need to create an equation. Our equation will be based on clues hidden in the text. So, what do we know?

- A number, aka y, is increased by 3. (y+3)

-That number is doubled. 'That number' refers to the answer of y+3. So, (y+3)x2.

-Finally, the end result is -8.

Great! Now we know our equation: 2(y+3)=-8. We need to figure out what y equals, so let's isolate the y term with some algebra.

2(y+3)=-8; Original formula

2y+6=-8; Distribute the (y+3)

2y=-14; Carry the 6 to the other side of the equation.

y=-7: Divide

Thus, our mysterious number is -7. Hope this helps:)))

£56

step-by-step explanation:

u divide 24 by 3 and u get 8 so if u do 8 time 7 or 8+8+8+8+8+8+8 u get 56 and 56 divided by 7 is 8.
