(x-3 / 5x) + 20 = x / 2 solve the equation I'm begging you. Please do it,

2*(X-3/5X)+2*20=X
2*2/5x+40=x
40=1/5x
200=x

(x + 5) multiply 3 = 5x series equation

(x + 5) times 3 = 5x
3x+15=5x
15=5x-3x
2x=15
x=7.5

(x + 3) * 2 = 5x-3, this is the equation!

Well *Is this a multiplier or a square?
Multiplication sign: 2x + 6 = 5x-3
3x=9
x=3

Given that 3 is the solution of the equation 5x-4a = 9 about X, then the value of a is?

"Please Qi" Hello, I'm glad to answer for you!
Substituting x = 3 into 5x-4a = 9, we get
5×3-4A=9
15-4A=9
4A=6
A=1.5

12. Store a and store B sell the same goods at the same price, and each of them offers different preferential schemes: after purchasing 100 yuan goods in store a, 90% of the original price will be charged for the goods they buy again; after purchasing 50 yuan goods in store B, 95% of the original price will be charged for the goods they buy again. How can customers choose a store to get more preferential treatment? 1) When the cumulative purchase is more than 100 yuan but less than 150 yuan, which store will spend less? 2) When the cumulative shopping is just 150 yuan, which store will cost less?

As a result, the number of items sold by store B is twice that of store a, and the total profit is 8000 yuan more than that of store A. how many items do store a and store B sell?

17. If the cost of a commodity is reduced by 8% and the retail price remains unchanged, the profit margin will increase from the current M% to (M + 10)% Here's my calculation: Let the cost be X m%x=(m+10)%-92%x The result is m = 115 The other answers are m = 15. I want to know what's wrong with my problem-solving process. (my idea is basically: retail price remains unchanged. Cost * profit margin = retail price). I wonder where to reduce 100%?
