Answer 1

Ответ:

Пошаговое объяснение:

1)3у-6=6

3у=6+6

3у=12

у=12:3

у=4

2)5у-4=21

5у=21+4

5у=25

у=25:5

у=5

3)-8у+3= -61

-8у=-61-3

-8у=-64

у=-64:(-8)

у=8

4)3-6х=27​

-6х=27-3

-6х=24

х=24:(-6)

х=-4

Answer 2

To solve each of these equations for у or х, follow these steps:

1. 3у - 6 = 6 Add 6 to both sides to isolate у. 3у = 6 + 6 3у = 12 Now, divide by 3 to find the value of у. у = 12 / 3 у = 4

2. 5у - 4 = 21 Add 4 to both sides to isolate у. 5у = 21 + 4 5у = 25 Now, divide by 5 to find the value of у. у = 25 / 5 у = 5

3. -8у + 3 = -6 Subtract 3 from both sides to isolate у. -8у = -6 - 3 -8у = -9 Now, divide by -8 to find the value of у. у = -9 / -8 у = 9/8 or 1.125

4. 3 - 6х = 27 Subtract 3 from both sides to isolate х. -6х = 27 - 3 -6х = 24 Now, divide by -6 to find the value of х. х = 24 / -6 х = -4

So, the solutions to the equations are:

1. у = 4
2. у = 5
3. у = 9/8 or 1.125
4. х = -4
