Question

1)40+2x=3x-15
2)9x = 8x - 6 - X
3)5(y+3)=10
4\3x - 4 + 2x= 6 +2x - 4
5)3(2x+8) - (5x+2) = 0
Срочно ​

Answer 1

Ответ:

1) 2х–3х=–15–40

–х=–55

х=55

2) 9х = 8х–6–х

9х–8х+х=–6

2х=–6

х=–3

3) 5(у+3)=10

5у+15=10

5у=10–15

5у=–5

у=–1

4) 3х–4+2х=6+2х–4

3х+2х–2х=–4+6+4

3х=6

х=2

5) 3(2х+8)–(5х+2)=0

6х+24–5х–2=0

6х–5х=0+2–24

х=–22
