How fast is 5x-2 = - 7x + 8

12x=10
x=10/12=5/6

How about 7x-6 = - 5x

7X-6=-5X
7X+5X=6
12X=6
X=0.5

How to calculate 7x 8 = 5x-4

7×8=5x-4
56=5x-4
5x=56+4
5x=60
x=60÷5
x=12

How to calculate 5x + 0.3 = 7x-1.3?

5X+0.3=7X-1.3
0.3+1.3=7X-5X
2.6=2X
X=1.3

How to calculate x-3 / 7X-2 / 5x = 60

x-3/7x-2/5x=60
(1-3/7-2/5)x=60
6/35x=60
x=60÷6/35
x=350

Just a few questions, 1. Calculate (x ^ 2 + 5x + 7) / (x + 2) - (x ^ 2 + 7x + 11) / (x + 3) 2. (b ^ 3 / A ^ 3-A ^ 3 / b ^ 3) / (b ^ 3 / A ^ 3 + A ^ 3 / b ^ 3-2)/
2.(b^3/a^3-a^3/b^3)/[(b^3/a^3)+(a^3/b^3)-2]/[1+(a^3/b^3)]

Question 1: first, decompose x ^ 2 + 5x + 7 into (x + 2) ^ 2 + (x + 3), and then decompose x ^ 2 + 7x + 11 into (x + 3) ^ 2 + (x + 2)
Then, the denominator is (x + 2) (x + 3), the molecule is (x + 2) ^ 2 (x + 3) + (x + 3) ^ 2 - (x + 3) ^ 2 (x + 2) - (x + 2) ^ 2, the common factor (x + 2) ^ 2 and (x + 3) ^ 2 are extracted, the molecule is (x + 2) ^ 3 (x + 3) ^ 3, and the result is obtained after reduction
（x+2）^2（x+3）^2.
In the second question, divide all the brackets to get the three parts (b ^ 6-A ^ 6) / A ^ 3 * B ^ 3 B ^ 6 + A ^ 6-2 * a ^ 3 * B ^ 3 B ^ 3 + A ^ 3 / b ^ 3 connected by a division sign. In the first part, B ^ 6-A ^ 6 is transformed into (b ^ 3 + A ^ 3) * (b ^ 3-A ^ 3) and the second part is transformed into (b ^ 3 + A ^ 3) ^ 2

3. Solve the equation X-1 / 4x = 2 / 3 x △ 3 / 5 = 3 / 4 1 / 5x = 25%

X-1/4X=2/3
3x/4=2/3
x=8/9
X÷3/5=3/4
x=3/4×3/5
x=9/20
1/5X=25%
x=1.25

5x = 25 * 4-15x to solve the equation
7x-x + 2 * 3 = 29.4 and (28.8 + 5.5x + 3.2) / 2 = 71

5x+15x=25*4
20x=100
x=100÷20
x=5

Solve the equation: 15x-6 = 5x, find X

15x-6=5x
15x-5x=6
10x=6
x=6÷10
x=0.6
