Answer:
n is equal to 26
Step-by-step explanation:
Equation: n+ n + (n+2) +(n+2) = 108
so: 2n + 2(n+2) = 108
2n + 2n + 4 = 108
4n + 4 = 108
4n = 108 - 4
4n = 104
n = 104/4
n = 26
Answer:
x = 18 y = 10
Step-by-step explanation:
let the first number be x
let the second number be y
x = y + 8..... equation 1
2x + y = 46.... equation 2
x is the larger number
y is the smaller number.
Rearrange the equation and add equation 1 to equation 2.
x - y = 8
+ 2x + y = 46
-------------------
3x + 0 = 54
3x = 54
divide both sides by 3
x = 54/3
x = 18
Substitute x = 18 into equation 1
x = y + 8
18 = y + 8
collect like terms
y = 18-8
y = 10
Any number over its self. for example 1,999/1,999
