Question

Помогите пожалусто !! решить уравнения

1) 4х+5(3 - 2х) =5 - 11х

2) 19-2(3х + 8) =2х - 37

Answer 1

1) 4х+5(3-2х) = 5-11х
4x+15-10x = 5-11x
4x-10x+15 = 5-11x
-6x+15 = 5-11x
15-5 = 6x-11x
10 = -5x
x = 10:(-5)
x = -2
Ответ: x = -2

2) 19-2(3х+8) = 2х-37
19-6x-16 = 2x-37
19-16-6x = 2x-37
3-6x = 2x-37
3+37 = 2x+6x
40 = 8x
x = 40:8
x = 5
Ответ: x = 5
