3/4x - 4 = 7 + 1/2x 3/4x = 11 + 2/4x 1/4x = 11 x = 44
4x + 3 cannot equal 4x + 12:4x + 3 = 4x + 12 (given)3 = 12 (subtract 4x from both sides)
1/4X+1/3=2 Subtract 1/3 1/4X=1 2/3 (I am now stuck, sorry, and I hope this helped a bit)
The algebraic formula [-4x - 3 = 17]is equal to -4x = 204x = -20x = -5
8x + 15
If 4x + 7 = 3... then x must equal -1
3/4x - 4 = 7 + 1/2x 3/4x = 11 + 2/4x 1/4x = 11 x = 44
5 1/3 = 4x/3 + 4 1 1/3 = 4x/3 4/3 = 4x/3 x = 1
4x + 3 cannot equal 4x + 12:4x + 3 = 4x + 12 (given)3 = 12 (subtract 4x from both sides)
1/4X+1/3=2 Subtract 1/3 1/4X=1 2/3 (I am now stuck, sorry, and I hope this helped a bit)
You can work this out with long division, by checking to see if (x2 - 1) is a factor of (2x4 + 4x3 - x2 + 4x - 3). It is. Unfortunately, the WikiAnswers system is somewhat limited in depicting things such as long division, so we won't be able to represent it here. In short though, (2x4 + 4x3 - x2 + 4x - 3) / (x2 + 1) is equal to 2x2 + 4x - 3. which means that: (x2 + 1) / (2x4 + 4x3 - x2 + 4x - 3) = (x2 + 1) / (x2 + 1)(2x2 + 4x - 3) = 1 / (2x2 + 4x - 3)
The algebraic formula [-4x - 3 = 17]is equal to -4x = 204x = -20x = -5
If 4x + 3 = 9, then 4x must equal 6. Therefore x=1.5
8x + 15
3 over 12 and 1 over 12 are not equal.
Depending on what your question was, there are different answers: 4x + 4 = 7x - 3 7x - 4x = 4+3 3 x = 7 x =7/3 or 4x + 47x -3 = 0 51x = 3 x = 3/51 x=1/17
