1 / 3 x + 3 / 6 x = 1.4

1 / 3 x + 3 / 6 x = 1.4

1 / 3 x + 3 / 6 x = 1.4
5x = 1.4
X = 1.4 △ 5 / 6
X=1.68

3x-5 / 3x-5 / 4 = 52 + 2x-7 / 2 × 6 / 5 = 1

The first x = 29 / 2, the second x = 32 / 21

1 / 8 x + 3 / 8 x = 4

1 / 8 x + 3 / 8 x = 4
1 / 2 x = 4
x=4*2
x=8

3x of 8 + 3 = 2x of 2 + 3 of 2
[solving equation]

3x of 8 + 3 = 2x of 2 + 3 of 2 multiplied by 8 at the same time
3x+24=4x+12
4x-3x=24-12
x=12

How to solve 3 / 4 (4 / 3 (2X-4 / 1) - 8) = 3x / 2

From 3 / 4 [4 / 3 (x / 2-1 / 4) - 8] = 3x / 2
3[4/3（x/2-1/4）-8]=6x
3（2x/3-1/3-8）=6x
2x-1-24=6x
4x=-25
x=-25/4.

The solution equation is: 3x + x = 7 / 4, 3x-5 / 4 = 3 / 2, 1x-5 / 4 = 8

2 (3x - √ 2) square = 8 x =?

That is, (3x - √ 2) &# 178; = 4
3x-√2=±2
3x=√2±2
x=(√2-2)/3,x=(√2+2)/3

2 * (the square of x) + 3x = 8 to find x

2x²+3x=8
2x²+3x-8=0
X & sup2; + 3x / 2-4 = 0
(x+3/4)²-73/16=0
(x+3/4)²=73/16
x+3/4=±√73/4
x=(-3±√73)/4

The solution equation (1) x + 3914 = 5.375 (2) x-745 = 427 (3) 34-0.6 + x = 1120 (4) 8-x = 7.5-323

（1）x+3914=5.375    x+3914-3914=5.375-3914             x=14156；（2）x-745=427 x-745+745=427+745    ...

Solve the equation, 1 and 2 / 3: x = 25 4.8: x = 1 and 1 / 5: 2

1 and 2 / 3: x = 25
X = 1 and 2 / 3 △ 25 = 1 / 15
Both sides are the same × 2x
9.6=6x/5
x=8
