Answer:

3) a = 4

4) m = 10

5) x = 2

6) (correct as is)

9) t = 14

Step-by-step explanation:

3:

Step 1: Add 4 to both sides.

  • [tex]8+4=3a-4+4[/tex]
  • [tex]12=3a[/tex]

Step 2: Divide both sides by 3.

  • [tex]12/3 = 3a/3[/tex]
  • [tex]a = 4[/tex]

4:

Step 1: Subtract 9 from both sides.

  • [tex]m/5 + 9 - 9 = 11 - 9[/tex]
  • [tex]m/5 = 2[/tex]

Step 2: Multiply both sides by 5.

  • [tex]m/5 * 5 = 2 * 5[/tex]
  • [tex]m = 10[/tex]

5:

Step 1: Subtract 13 from both sides.

  • [tex]13+7x-13=27-13[/tex]
  • [tex]7x=14[/tex]

Step 4: Divide both sides by 7.

  • [tex]7x/7 = 14/7[/tex]
  • [tex]x=2[/tex]

6: (correct as is)

9:

Step 1: Subtract 5t from both sides.

  • [tex]42+5t-5t=8t-5t[/tex]
  • [tex]42=3t[/tex]

Step 2: Divide both sides by 3.

  • [tex]42/3=3t/3[/tex]
  • [tex]t=14[/tex]
