Answer:
x=6
Step-by-step explanation:
x + 6 = x + x original problem
x + 6 = 2x combine like terms
-x = -x subtract x from both sides to have like terms on each side
6 = x solution
X=the number we have to find.
This expression "2(x+9)" is when the sum of a number and nine is doubled.
If the result is seven less than the number, we will have: x-7
We can suggest the following equation:
2(x+9)=(x-7)
2x+18=x-7
2x-x=-7-18
x=-25
answer: the number would be: -25.
21 = 4.8
8 x 2.1 = 16.8 - 12 = 4.8
