Question

найдите корень уравнения:

1) $\frac{3m + 5}{4} = \frac{5m + 1}{3}$

2) $\frac{5x + 3}{5} = \frac{x - 5}{8}$

Answer 1

Ответ:

1)m = 1 2)x = -1.4

Объяснение:

1)(3m+5)/4 = (5m+1)/3

(5m + 1) * 4 = (3m + 5) * 3

20m + 4 = 9m + 15

20m - 9m = 15 - 4

11m = 11

m = 11 : 11

m = 1

2)(5x+3)/5 =(x -5)/8

8(5x+3) =5(x -5)

40x +24 =5x -25

40x -5x = -25 -24

35x = -49

x = -1.4
