Question

Срооооооочно дайте решение даю14б (4x+1)(x+5)-(2x+1)(2x-30)=58

Answer 1

(4х+1)(х+5)-(2х+1)(2х-30)=58
4х+1х+5-2х-2х-30=50
4х+1х-2х-2х=50-5+30
-1х=75
х= -75
ОТВЕТ: -75

Answer 2

(4х+1)(х+5)-(2х+1)(2х-30)=58
(4х²+20х+х+5)-(4х²-60х+2х+30)=58
4х²+20х+х+5-4х²+60х-2х-30=58
79х-25=58
79х=58+25
79х=83
х=83/79=1 4/83
