4n-3=5 add 3 both sides 4n=8 divide by 4 both sides n=2
4n+13=1 -13 -134n=-12/4 /4n=-3
To solve for n in the equation 4n + 3 = 19, you first need to isolate the variable n. Start by subtracting 3 from both sides of the equation to get 4n = 16. Then, divide both sides by 4 to find n = 4. Therefore, the solution to the equation is n = 4.
4n + 9 = -3 Now, we take away 9 from both sides 4n = -12 Now divide by 4 n = -3
n3 + 3n2 + 4n + 12 = (n3 + 3n2) + (4n + 12) = n2(n + 3) + 4(n + 3) = (n2 + 4)(n + 3).
