2x - x = 3 - 1
1x = 2/1
x = 2
Right.
6n + 4 = n - 11
6n + n = 11 - 4
5n = 7
n = 2
is it correct???? (sorry but I'm trying to do the problems and I'm just making sure to see if I'm correct so I may post a few problems, don't worry not too much)
No. You forgot the minus sign.
6n + 4 = n - 11
5n = -4 - 11
5n = -15
n = -3
how did you got -3???? i got 3
Did you check your answer to make sure it satisfies the original equation?
-3 does, 3 does not.
To solve the equation 2x - x = 3 - 1, we can follow these steps:
1. Combine like terms on both sides of the equation. On the left side, we have 2x - x, which simplifies to x. On the right side, 3 - 1 simplifies to 2.
The equation now becomes:
x = 2
2. Divide both sides of the equation by 1. In this case, dividing by 1 does not change the value of x.
The equation remains:
x = 2
So, the solution to the equation 2x - x = 3 - 1 is x = 2.
