Answer:

x = 9

1/4(8x+12) =21

1/4 * 8x = 2x

1/4 * 12 = 3

2x + 3 = 21

21 - 3 = 18

2x = 18

18/2 = 9

Answer:

x=9

Step-by-step explanation:

  • Try first by multiplying the 8x and 12 in the brackets by 1/4 so it will be:

2x+3=21

  • Now subtract 3 from each side

2x=18

  • Then divide each side by 2

x=9
