Question

prosze musze zdać na 4 !!!!!! Musze się dostać do technikum

Answer 1

a) 4 (x – 3/2) + 3(2 1/2 - x) = 3/4x – 2

4x – 6 + 15/2 – 3x = 3/4x – 2 /*4

16x – 24 + 30 – 12x = 3x – 8

16x – 12x – 3x = -8 – 30 + 24

x = - 14

 

b) (2x + 4)/4 – x = - (3x – 6)/2 /*4

2x + 4 – 4x = - 6x + 24

2x – 4x + 6x = 24 – 4

4x = 20/4

x = 5
