N+18=30. Subtract 18 both sides
N=12
To solve the equation n + 3x6 = 30, first calculate 3x6, which equals 18. Then subtract 18 from both sides of the equation to isolate n. Thus, n = 30 - 18, which simplifies to n = 12.
n + 6 = 18 n = 12
n + 5 = 18 n = 13
n + 18 = 27 subtract 18 to 18 and 27 18-27=9 n = 9
N=3.
To solve the equation n + 3x6 = 30, first calculate 3x6, which equals 18. Then subtract 18 from both sides of the equation to isolate n. Thus, n = 30 - 18, which simplifies to n = 12.
n + 6 = 18 n = 12
n + 5 = 18 n = 13
Oh, dude, if 5 plus n equals 23, then n must be 18, right? So, if you wanna find out what n minus 5 equals, just subtract 5 from 18 and you get 13. Easy peasy lemon squeezy.
n + 18 = 27 subtract 18 to 18 and 27 18-27=9 n = 9
N=3.
It depends on the value of n.
if you put in what the problem equals then it can be answered
3n+6=18 n+2=6 n=4
It is a linear equation in one variable, n.
For n+9=18, the answer would be n=9 because n+9=18 also mean 18-9=n so 18-9=9
n = 5 so both sides are equal
