Solving the equation: 2x-1 / 3-10x + 1 / 12 = 2x + 1 / 4 Will increase the reward of wealth

2x-1 / 3-10x + 1 / 12 = 2x + 1 / 4
Multiply both sides by 12 at the same time
4(2x-1)-(10x+1)=3(2x+1)-12
8x-4-10x-1=6x+3-12
-2x-6x=5-9
-8x=-4
X = 1 / 2

The method of solving the equation 2x ^ 3-x ^ 2-25x-12 = 0

2x^3+x^2-2x^2-x-24x-12=0
(2x+1)(x^2-x-12)=0
(2x+1)(x-4)(x+3)=0
x=-1/2,4,-3

Solving equation 25X ^ 2-36 = 0 (2x-5) ^ 2 - (x + 4) = 0

25x^2=36
x^2=36/25
x=6/5 x=-6/5
(2x-5)^2-(x+4)^2=0
(2x-5+x+4)(2x-5-x-4)=0
(3x-1)(x-9)=0
∴x=1/3 x=9

Solution equation: 7.8 x + 3.2X = 12.1.34 + 25X = 910

7.8 x+3.2x=12.1
11x=12.1
x=12.1÷11
x=1.1
34+25x=910
25x=910-34
25x=876
x=876÷25
x=35.04
