solve the equation -2x+1=5-2x can you please show me some videos of how i can solve them
-2x+1=5-2x
-2x + 2x = 4
No solution.
http://www.khanacademy.org/math/algebra
is this correct
3x-3=0
3x-3+0=0
3x-3=0
f(x)=3x-3
table:
1 f(1)=3(1)-3 1,0
-1 f(-1)=3(-1)-3 -1,-6
2 f(-2)= 3(-2)-3 -2,-9
which one for the videos will sum up pretty much these equations?
I don't know. Post your last question as a new question, please.
what do you mean?
To solve the equation -2x + 1 = 5 - 2x, we will begin by isolating the variable x on one side of the equation.
1. Start by moving all the terms containing x to one side of the equation.
-2x + 2x + 1 = 5 - 2x + 2x
The -2x and the +2x on the left side cancel each other out, leaving us with:
1 = 5
2. Now, let's analyze the equation. We can see that 1 is never equal to 5, meaning there is no solution to this equation. This is called an inconsistent equation.
So, the equation -2x + 1 = 5 - 2x has no solution.
