X + 6 = 8 + 7x
First, use the equality property to move the variable x to one side.
x + 6 = 8 + 7x
-x -x
You are left with: 6 = 8 + 6x
Use the equality property again
6 = 8 + 6x
-8 -8
-2 = 6x
Divide each side by 6: and your solution is -2/6, which simplifies to -1/3

Im NOT sure this is the correct answer but it is the one i found.
Answer:
Step-by-step explanation:
First of all, you have to set up the equation
2x^2 + x -1 = 2 Subtract 2 from both sides
2x^2 + x - 1 - 2 = -2+2 Combine
2x^2 + x - 3 = 0 This factors.
(2x + 3)(x -1 ) = 0
Either
2x + 3 = 0 Subtract 3 from both sides
2x = - 3 Divide by 2
2x/2 = - 3/2
x = - 3/2 which you already know
or
x - 1 = 0 Add 1
x - 1 + 1 = 1
x = 1
the other answer is x = 1
