Answer 1

Answer:

$5) \: 7(x - 2) + 1 = - 34 \\ 7x - 14 + 1 = - 34 \\ 7x = - 34 + 13 = - 21 \\ x = - 21 \div 7 = - 3 \\ 6)10x + 4 - 8x = 2(x - 1) \\ 2x + 4 = 2x - 2 \\ 0x = - 6 \\ no \: solution \\ 8)5(x - 3) + 1 = 5x - 14 \\ 0x = 0 \\ no \: solution \\ 9)2x + 3 = 5x + 3 - 3x \\ 0x = 0 \\ no \: solution \\ 11)x + 2x + 1 = 3x + 5 \\ 0x = 4 \\ no \: solution \\ 12) - 3 = \frac{ - 2x + 4}{ - 4 } \\ 12 = - 2x + 4 \\ 8 = - 2x \\ - 4 = x \\ thank \: you$

Answer 2

Answer:

5. 7(x - 2) + 1 = -34

7x - 14 + 1 = -34

7x - 13 = -34

7x = -34 + 13

7x = -21

x = -21/7 = -3

6. 10x + 4 - 8x = 2(x - 1)

2x + 4 = 2x - 2

Cancel 2x means this equation has no solution

8. 5(x - 3) + 1 = 5x - 14

5x - 15 + 1 = 5x - 14

5x - 14 = 5x - 14

5x - 5x = -14 + 14

0

9. 2x + 3 = 5x + 3 - 3x

2x + 3 = 2x + 3

2x - 2x = 3 - 3

0

11. x + 2x + 1 = 3x + 5

3x + 1 = 3x + 5

Cancel 3x means this equation has no solution

12. -3 = -2x + 4/-4

-3 × (-4) = -2x + 4

12 = -2x + 4

12 - 4 = -2x

8 = -2x

8/-2 = x

-4 = x
