Let, the age of Daniel = x
Then, Age of Kevin = x + 3
Two years ago, (x + 1) = 4(x - 2)
x + 1 = 4x - 8
4x - x = 1 + 8
3x = 9
x = 9/3
x = 3
In short, Your Answer would be 3 Years
Hope this helps!
I believe the first on is -1 and the second one is NO SOLUTION
I'd be glad to answer if i knew the question
it depends how long the width and the length is. If the length is 5 cm and the width is 4 cm the perimeter will be 18cm. All you have to do is 5 doubled because there 2 sides for the length and 4 doubled because there are 2 sides for the width. I hope I have answered your question. XD
3(3x - 8) + 4x = -2(12 - 7x) - x
9x - 24 + 4x = -24 + 14x - x <em>distributed 3 on the left and -2 on the right</em>
- 24 + 13x = -24 + 13x <em>added like terms on the left and the right</em>
<u> -13x</u> <u> -13x </u>
-24 = -24
TRUE
A true statement means infinitely many solutions (aka All Real Numbers)
