The first equality is: x2 - 5 = -4x2 which gives 5x2 - 5 = 0 which is equivalent to x2 - 5 = 0 The second equality is: -4x2 = 3x which gives 4x2 + 3x = 0 The two results are inconsistent.
what does 15+2x=5+3x equal to in math
4x + 5 = 3x + 84x-3x + 5 - 5 = 3x - 3x + 8 -5x = 3
3x + 5 = 20Subtract 5 from each side:3x = 15Divide each side by 3:x = 5
If you meant (x/5) + 2 = 3x/5 = 1x =5-----------------If you meant x/(5+2) = 3x/(7) = 3x = 21
