X=7
But to show your work you would put
-1x=7
Then divide -1x by -1 and 7 by -1 to cancel it out, and you get x=8
2x+2 would be the expression
Answer:
<em>1, 2, 3, 6</em>
Step-by-step explanation:
The given equation is,


We need to to find all the whole values of a for which the solution of the equation i.e x will be a whole number.
We know that when a number is divided by one of its factor it leaves a remainder of 0 or the result we get is a whole number.
That is why, we need a as one of the factors of 6, i.e 1, 2, 3, 6 in order to get x as a whole number.
Answer:
A is correct.
x>5 means all numbers greater than BUT not equal to 5.
The open circle means "not equal".
So, A is correct.
Hope this helps!
