J= 4k? – 20 and k = 3/2l+3
a. j when l equals 4

you can't solve x because it is 2 linear equation and you only have one equation

12

step-by-step explanation:

replication and blocking

step-by-step explanation:

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218
