Answer:
x= 5
Explanation:
4x-6=x+9
Move the -6 to the other side of the equation by adding 6 to each side.
4x-6 + 6 =x+9 + 6
4x = x+15
Now move the x on the right side of the equation to the left side of the equation by subtracting x from each side.
4x - x = x + 15 - x
3x = 15
Now to isolate the x, divide both sides of the equation by 3.
3x/3 = 15/3
x = 5
Check your answer by substituting x = 5 into the original equation:
4x-6=x+9
4(5) - 6 = 5 + 9
20 - 6 = 14
14 = 14 >>> so this answer, x=5, is correct.
