Answer 1

Explanation:

♤ 3(b-5) = 27

=> 3b - 15 = 27

=> 3b = 27 + 15 = 42

=> b = 42/3

=> b = 14 (Ans)

♤ 2x/3 = 6

=> 2x = 6 × 3 = 18

=> x = 18/2

=> x = 9 (Ans)

♤ 2(n + 5) = 15

=> 2n + 10 = 15

=> 2n = 15 - 10 = 5

=> n = 5/2

=> n = 2.5 (Ans)

♤ a + a + a + a = 24

=> 4a = 24

=> a = 24/4

=> a = 6 (Ans)

♤ 4c + 6 = 18

=> 4c = 18 - 6 = 12

=> c = 12/4

=> c = 3 (Ans)
