4n + 3 = 19Subtract 3 from each side:4n = 16Divide each side by 4:n = 4
8n-2+4n = 66-5n 8n+4n+5n = 66+2 17n = 68 n = 4
It is 4n
4n - 7n = 21(4-7) n =21-3n = 21divide both sides by -3n = -7
4n = 3n + 44n - 3n = 3n - 3n + 4n = 4check:4n = 3n + 44(4) =? 3(4) + 416 =? 12 + 416 = 16 True
4n + 3 = 19Subtract 3 from each side:4n = 16Divide each side by 4:n = 4
4n-8
Oh, dude, so, like, when you multiply 8 by 0, you get 0, not 4n. It's like trying to make a sandwich with just bread - you're missing the filling! Maybe check your math or see if there's more to the equation that got lost along the way.
8n-2+4n = 66-5n 8n+4n+5n = 66+2 17n = 68 n = 4
It is 4n
8+4n=-4 algebra gives us 4n=-12 n=-3
4n - 7n = 21(4-7) n =21-3n = 21divide both sides by -3n = -7
4n = 3n + 44n - 3n = 3n - 3n + 4n = 4check:4n = 3n + 44(4) =? 3(4) + 416 =? 12 + 416 = 16 True
It is simply: 4n as an algebraic term
4 + 4n - 12 = 4n - 8
The nth term IS 4n + 3 ie 4 times n and then add 3.
n = 1 7n + 6n - 5 = 4n + 4 13n - 5 = 4n + 4 13n - 4n - 5 = 4n - 4n + 4 9n - 5 = 4 9n -5 + 5 = 4 + 5 9n = 9 n = 1
