Question

solve the following equation.
(A) 3(n-5)=-21
(B) 3-2(2-y)=7

Answer 1

Answer:

(A) n = 12  (B) y = 4

Step-by-step explanation:

(A) 3(n-5)=-21

=> 3*n - 3*5 = 21

=> 3n - 15 = 21

=> 3n = 21 + 15

=> 3n = 36

=> n = 36/3

=> n = 12

(B) 3-2(2-y)=7

=> 3 - 2*2 + 2*y = 7

=> 3 - 4 + 2y = 7

=> -1 + 2y = 7

=> 2y = 7 + 1

=> 2y = 8

=> y = 8/2

=> y = 4
