Question on the picture:)

a. No

b. Yes

Step-by-step explanation:

a.

x - 4 = 12

x - 4 + 4 = 12 + 4

x = 16

16 ≠ 8

Therefore, the following value given for problem a is not a solution to the given equation.

b. (3 + x)/4 = 3

(3 + x)/4 * 4 = 3 * 4

3 + x = 12

3 + x - 3 = 12 - 3

x = 9

9 = 9

Therefore, the following value given for problem b is a solution to the given equation.

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.
