Answer 1

Ответ:

вот решение

Пошаговое объяснение:

1) 14x+4x-48=240

14x+4x=240+48

18x=288

x=16

2) 25b-7b-9=279

25b-7b= 279+9

18b=288

b=16

3)16a-7a+96=222

16a-7a=222-96

9a=126

a=14

4)20y+5y+y+19=227

20y+5y+y= 227-19

26y=208

y=8

Answer 2

1) 14x+4x-48=240

18x = 288

x = 288/18 = 16

2) 25b-7b-9=279

18b = 288

b = 16

3) 16a - 7a + 96 = 222

9a = 126

a = 126 / 9 = 14

4) 20y + 5y + y + 19 = 227

26y = 208

y = 8

Answer 3

It looks like you've provided a set of equations. Let's solve them one by one:

1. 14x + 4x - 48 = 240

Combine like terms on the left side: 18x - 48 = 240

Add 48 to both sides: 18x = 288

Divide by 18: x = 16

2. 25b - 7b - 9 = 279

Combine like terms on the left side: 18b - 9 = 279

Add 9 to both sides: 18b = 288

Divide by 18: b = 16

3. 16a - 7a + 96 = 222

Combine like terms on the left side: 9a + 96 = 222

Subtract 96 from both sides: 9a = 126

Divide by 9: a = 14

4. 20y + 5y + y + 19 = 227

Combine like terms on the left side: 26y + 19 = 227

Subtract 19 from both sides: 26y = 208

Divide by 26: y = 8

So, the solutions for the variables are:

1. x = 16
2. b = 16
3. a = 14
4. y = 8
