Answer:
x = -1
Step-by-step explanation:
Step 1: Combine like terms on the right side
6 - 8x = 7x - 9x + 12
6 - 8x = -2x + 12
Step 2: Add 8x to both sides
6 - 8x + 8x = -2x + 12 + 8x
6 = 6x + 12
Step 3: Subtract 12 from both sides
6 - 12 = 6x + 12 - 12
-6 = 6x
Step 4: Divide both sides by 6
-6 / 6 = 6x / 6
-1 = x
Answer: x = -1
Answer:
x = -1
Step-by-step explanation:
6-8x=7x-9x+12
To solve the equation, we will follow the step below;
First we will collect the like terms, this implies that all the number with x variables will be taken to the left-side while all the constant will be taken to the right-hand side.
That is;
6-8x=7x-9x+12
-8x -7x + 9x = 12 - 6
-6x = 6
Divide both-side of the equation by -6 to get the value of x
[tex]\frac{-6x}{-6}[/tex] = [tex]\frac{6}{-6}[/tex]
(On the left-hand side of the equation -6 at the numerator will cancel-out -6 at the denominator leaving us with just x, while on the right-hand side of the equation 6 will be divided by -6)
x = [tex]\frac{6}{-6}[/tex]
x = -1
