Answer 2

${\huge{\underline{\boxed{\red{\mathcal{Answer}}}}}}$

1. -2x + 8 = 2x - 4

=> 8 + 4 = 2x + 2x

=> 4x = 12

=> x = 3

2. 5y = 10y - 30

=> 10y - 5y = 30

=> 5y = 30

=> y = 6

3. 4(y - 3) = y + 9

=> 4y - 12 = y + 9

=> 4y - y = 9 + 12

=> 3y = 21

=> y = 7

4. 6x + 20 = 40 + 8x

=> 8x - 6x = 40 - 20

=> 2x = 20

=> x = 10

5. 15x - 4(2x + 14) = 0

=> 15x - 8x - 56 = 0

=> 7x = 56

=> x = 8

6. -3y - 5(y + 4) = 4

=> -3y - 5y - 20 = 4

=> 8y = 20 - 4

=> 8y = 16

=> y = 2

7. 3(x - 4) + 2(2x + 1) = 11

=> 3x - 12 + 4x + 2 = 11

=> 7x = 11 + 10

=> 7x = 21

=> x = 3

8. 4(5 - x) + 2x - 10 = -2x + 10

=> 20 - 4x + 2x - 10 = -2x + 10

=> 20 - 10 - 10 = -2x + 4x - 2x

=> 0 (x has infinite values)

9. 4x = 3x + 6

=> 4x - 3x = 6

=> x = 6

HOPE IT HELPS!!!
