how do you solve a question like
4n-2n=18
4n-2n = 2n
2n=18
divide both sides by 2 to isolate the n
n=9
thanks
To solve the equation 4n - 2n = 18, you can follow these steps:
Step 1: Combine like terms on each side of the equation.
4n - 2n = 18
(4 - 2)n = 18
2n = 18
Step 2: Simplify the equation by dividing both sides by the coefficient of n, which is 2.
2n/2 = 18/2
n = 9
Therefore, the solution to the equation 4n - 2n = 18 is n = 9.
