I wish I could see your answer in the picture. Then we could put it into the original equation and see if it checks.
It won't, because you made a slight mistake in your first line, where you were eliminating the parentheses on the right side:
-4(x- 3) = -4x +12 . . . . . not -4x -12 .
That should get you all fixed up.
When you combine like terms from your first line, your second line will be 4x + 6 = 30 - 4x
and it's all smooth sailing from there.
The product of blank and four is equal to the product of eight & twelve
Answers
Let us say that this blank is x
So:
Simplyfying that:
Dividing 4 on both sides:
So this blank would be
So,
We can write this as an equation.
x * 4 = 8 * 12 4x = 8(12)
Distribute. 4x = 96
Divide both sides by 4. x = 24
Check. 24 * 4 = 8 * 12 96 = 96 This checks.

Mo-Qui has studied Spanish for half an hour longer than he studied History.If He spent 2 hours and 15 min studying for Spanish, but isn't finished yet, write an inequality to show how the amounts of time studying each subject are related.
Answers
So,
Let s represent the time Mo-Qui spent studying Spanish and h represent the time Mo-Qui spent studying History.
s = h + 30 s > 2 hrs. 15 mins. (he isn't done yet)
Substitute 2 hrs. 15 mins. = h + 30 mins.
Subtract 30 mins. from both sides 1 hr. 45 mins. = h
However, s > 2 hrs. 15 mins., so h must be more than 1 hr. and 45 mins.
h > 1 hr. 45 mins.
