Answer 1

Step-by-step explanation:

1.

$2x + 3 = 7 \\ 2x = 7 - 3 \\ 2x = 4 \\ x = 2$

4.

$3x + 6 = 6 \\ 3x = 0 \\ x = 0$

2.

$3x + 2 = 23 \\ 3x = 21 \\ x = 7$

7.

$2x + 8 = 0 \\ 2x = - 8 \\ x = - 4$

5.

$4x + 5 = 17 \\ 4x = 12 \\ x = 3$

8.

$7x + 14 = 21 \\ 7x = 7 \\ x = 1$

3.

$5x + 12 = 53 \\ 5x = 41 \\ x = \frac{41}{5}$

6.

$6x + 7 = 25 \\ 6x = 18 \\ x = 3$

9.

$8x + 24 = 40 \\ 8x = 16 \\ x = 2$
