Question

Q2. Solve :
(a) 2(x + 4) = 12 (c) 3(n – 5) = – 21
(e) 4(2 – x) = 8

Answer 1

Explanation:

✨⭐GIVEN :-

(a) 2(x+4) = 12

= 2×x + 2×4 = 12

=. 2x + 8 = 12

=. 2x = 12

= x = 12/2 = 6

(c). 3(n-5)= -21

= 3×n -3×5 = -21

= 3n -15 = -21

= 3n = -21+15

= 3n = -6

= n = -6/3 = -2

(e). 4(2-x) = 8

= 4×2 - 4×x = 8

= 8-4x =8

= -4x = 8-8

= x = 0/-4 = 0

Hope this helps you
