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
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.
I got an answer of 43.75 (forty-three and three-fourths)The question in mathematical form is:4n - 1 = 174First, you get rid of the one like so:4n - 1 = 174+1 +1----------------4n = 175Now, divide by 4:4n = 175/4 /4-----------n = 43.75
7N - 4N = 24
