Question

решите уравнение:
(2x - 3) - (x - (3x - 4) = 6

Answer 1

(2х-3)-(х-(3х-4)=6
(2х-3)-(х-3х+4)=6
(2х-3)-х+3х-4=6
2х-3-х+3х-4=6
2х-х+3х=6+3+4
4х=13
х=13:4
х=3,25

Answer 2

(2x - 3) - (x - (3x - 4)) = 6
2х-3-(х-3х+4)=6
2х-3-(4-2х)=6
2х-3-4+2х=6
(2х+2х)-(3+4)=6
4х-7=6
4х=7+6
4х=13
х=13:4
х=3,25
