6(x + 4) = 8(x - 2)
First you can multiply out the brackets:
6(x + 4) = 8(x - 2)
6(x) + 6(4) = 8(x) - 8(2)
6x + 24 = 8x - 16
Now you can add 16 to both sides of the equation:
6x + 24 + 16 = 8x - 16 + 16
6x + 40 = 8x
Now you can subtract 6x from both sides of the equation:
6x + 40 - 6x = 8x - 6x
40 = 2x
Now divide by 2 for both equations:
40/2 = (2x)/2
20 = x
And so the final solution is:
x = 20
