Question

(5+2x):3=(х-3):5+(х+5):2

Answer 1

Сначала находим сколько будет после знака равно (х-3):5+(х+5):2 (1-3):5+(1+5):2 0,7:5+6:2 0,14+3=3,14 ищем сколько будет (5+2х):3=3,14 5+2х=3*3,14 5+2х=10,32 2х=10,32-5 2х=5,32 х=5,32:2 х=2,66

Answer 2

To solve the equation (5+2x)/3 = (x-3)/5 + (x+5)/2, we need to simplify and isolate the variable x.

First, let's simplify both sides of the equation:

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

Multiply both sides of the equation by the common denominator of 3, 5, and 2, which is 30:

30 * (5+2x)/3 = 30 * (x-3)/5 + 30 * (x+5)/2

After multiplying, we get:

10(5+2x) = 6(x-3) + 15(x+5)

Simplify further:

50 + 20x = 6x - 18 + 15x + 75

Combine like terms:

20x - 6x - 15x = 75 - 50 - 18

-x = 7

To isolate x, multiply both sides of the equation by -1:

x = -7

Therefore, the solution to the equation is x = -7.
