hujkImproved anwser:2x+6 = 7x-42x-7x = -4-6-5x = -10x = 2
4x = 42x+1Take the logarithm of each side of the equation:x log(4) = (2x+1) log(4)Divide each side of the equation by log(4) :x = 2x + 1Subtract 'x' from each side:x + 1 = 0Subtract ' 1 ' from each side:X = -1Check it out:4x = 42x+14(-1) = (?) 4(-2+1)4(-1) = 4(-1) yay!
(2x + 1)(2x + 1) or (2x + 1)2
2 plus 1-x divided by.
2x + 4 = 2 2x = -2 x = -1
