Question

I am thinking of a number, N.
Twice (N + 10) is the same as four times (N - 10).
a Write down an equation to show this.
b Solve the equation to find the value of N.​

Answer 1

Answer:

N = 30

Step-by-step explanation:

2(N + 10) = 4(N - 10)

2N + 20 = 4N - 40

20 + 40 = 4N - 2N

60 = 2N

N = 60 ÷ 2

N = 30
