Answer 1

Ответ:

(2х+1)/1,3=2,5/0,65

2х+1=(1,3*2,5)/0,65

2х+1=5

2х=5-1

2х=4

х=2

3,25/(4х-1,9)=13/0,4

4х-1,9=(3,25*0,4)/13

4х-1,9=0,1

4х=0,1+1,9

4х=2

х=0

Answer 3

It seems like you have provided two sets of equations, and you would like me to solve them. Let's go through each set step by step.

1. Equations: 22431 - 8465(2x+1) - 0.65 = 1.3 - 2.5(0.65) 90 - ecen 20 + 1 = 1.3 - 25(0.65)

Unfortunately, the first equation you provided is incomplete. It seems to be missing some terms, such as "ecen." Please provide the complete equation so that I can help you solve it.

2. Equations: 3.25 * 43 - 1.90 * 4(4x - 1.9) * 13 = 3.25 - 0.4 4x - 1.9 = 3.25 - 0.4 13 * (4x - 1.9) = 0.1 4x - 1.9 = 0.1 4x = 0.1 + 1.9 x = 2 / 4 x = 0.5

Based on the second set of equations, the solution for x is 0.5.
