How to solve 1-9 / 5x-2 = 6 / 5-x

How to solve 1-9 / 5x-2 = 6 / 5-x

Multiply both sides of the equation by 18
18-2(5x-2)=3(5-x)
18-10x+4=15-3x
-10x+3x=15-18-4
-7x=-7
x=1

2X + 5.4 = 15.4 7x-5x = 12.6 9-x = 15 / 14 (14 / 15 of the score) 12.75-5x = 3 / 4

2X + 5.3 = 15.4, that is, 2x = 10.1, x = 5.05, 7x-5x = 12.6, that is, 2x = 12.6, x = 6.3, 9-x = 14 / 15, that is, x = 9-14 / 15, x = 8 and 1 / 15. 12.75-5x = 3 / 4, that is, 5x = 12.75-0.75 = 12.75

9/25×5/9＋2/5x＝3/5
How to solve it

9/25×5/9＋2/5x＝3/5
1/5+2/5x=3/5
1+2x=3
2x=3-1
2x=2
x=1

-18/(-3)^2+5X(-1/2)^3-(-15)/5

Solution% d% a original formula% d% a = - 18 △ 9 + 5 × (- 1 / 8) + 3% d% a = - 2-5 / 8 + 3% d% a = 1-5 / 8% d% a = 3 / 8

A simple algorithm of 8.3/0.25

8.3/0.25
＝（8.3×4）÷（0.25×4）
＝33.2÷1
＝33.2

Simple algorithm of 1.5x [(0.6 + 1.25) x0.8]

=1.5×(0.6×0.8+1.25×0.8）
=1.5×(0.48+1)
=1.5×1.48
=2.22

A simple algorithm of 0.5x (4.2-0.8) - 0.45

0.5×(4.2-0.8)-0.45
=0.5×(4.2-0.8)-0.5×0.9
=0.5×(4.2-0.8-0.9)
=0.5×2.5
=1.25

Simple calculation of 18.4 △ 0.5 + 1.84

18.4÷0.5＋1.84
=18.4*2+18.4*1/10
=18.4*(2+1/10)
=18.4*21/10
=38.64

Simple calculation of 1.84 (18.4 △ 0.5) and 5.6 △ 35
Write it clearly so that people can understand it at a glance. You'd better answer both. I'm so worried,

1.84÷（18.4÷0.5）=(1.84÷18.4)÷0.5=0.2

A simple algorithm for [1 - (7 / 12 + 7 / 18)] / 5 / 36

The original formula = (36-36 * (7 / 12 + 7 / 18)) / 5 = (36-7 * 3 + 7 * 2) / 5 = (36-35) / 5 = 1 / 5
