Question

1) 6х+24=0 2)2х+3=3х-2 3)3(5-х)=11+2х​

Answer 1

Пошаговое объяснение:

1)

$6x + 24 = 0 \\ 6x = 0 - 24 \\ 6x = - 24$

x = -24:6=-4

2)

$2x + 3 = 3x - 2 \\ 2x - 3x = - 2 - 3 \\ - 1x = - 5$

x = -5:(-1)

x=5

3)

$3(5 - x) = 11 + 2x \\ 15 - 3x = 11 + 2x \\ - 3x - 2x = 11 - 15 \\ - 5x = - 4$

$- \frac{5}{1} \div (- \frac{4}{1} ) \\ - \frac{5}{1} \times (- \frac{1}{4}) \\ \frac{5}{4}$

Answer 2

Пошаговое объяснение:

1) 6х+24=0

6х=0-24

6х=-24

х=-4

2)2х+3=3х-2

2х-3х=-2-3

-х=-5

х=5

3)3(5-х)=11+2х

15-3х=11+2х

-3х-2х=11-15

-5х=-4

$x = \frac{4}{5} = 0.8$
