(ii) 21 - 3(x-7) = x =20

Answer 1

Step-by-step explanation:

Solve it (i) 2(3-2x) = 13

(ii) 21 - 3(x-7) = x =20

Answer 2

Answer:

So,

answer of (i) -7/4

(ii) -5

Step-by-step explanation:

SOLUTION

(i) 2 (3 - 2x) = 13

=> 6 - 4x = 13

=> -4x = 13 - 6

=> -4x = 7

=> x = -7/4

(ii) 21 - 3(x - 7) = x + 20

=> 21 - 3x - 21 = x + 20

=> -3x - x = 20

=> -4x = 20

=> x = 20/-4

=> x = -5
