solve 4(y-4)=8

Answer 1

1.

x / 4 + 1 = - 5 Subtract 1 to both sides

x / 4 + 1 - 1 = - 5 - 1

x / 4 = - 6 Multiply both sides by 5

x = - 6 * 4

x = - 24

2.

6 x + 29 = 5 Subtract 29 to both sides

6 x + 29 - 29 = 5 - 29

6 x = - 24 Divide both sides by 6

x = - 24 / 6

x = - 4

3.

- 21 a + 16a = - 5 a

4.

9 a - b - 2a - 10 b =

9 a - 2 y - b - 10 b =

7 a - 11 b

4 n + 7 + 2 n = 1

4 n + 2 n + 7 = 1

6 n + 7 = 1 Subtract 7 to both sides

6 n + 7 - 7 = 1 - 7

6 n = - 6 Divide both sides by 6

n = - 6 / 6

n = - 1

4 ( y - 4 ) = 8 Divide both sides by 4

y - 4 = 8 / 4

y - 4 = 2 Add 4 to both sides

y - 4 + 4 = 2 + 4

y = 6

Answer 2

Correction.

I forget - sign.

- 4 n + 7 + 2 n = 1

- 4 n + 2 n + 7 = 1

- 2 n + 7 = 1 Subtract 7 to both sides

- 2 n + 7 - 7 = 1 - 7

- 2 n = - 6 Divide both sides by - 2

n = - 6 / - 2

n = 3
