Question

4-2 (Z-4) = 1/2 (2Z+5)​

Answer 1

Given 4-(2(z-4))/2=1/2(2z+5)

Now by taking L.C.M of 1 and 3 is 3 12-2(z-4)/3 = (2z+5)/2

By cross multiplication we get 2(12-2z+8) = 3(2z+5) 40-4z

=6z+15 -10z=-25

z=25/10=5/2

Hope it'll help you..

Answer 2

Answer:

z = 11/4

Step-by-step explanation:

4-2(Z-4) = 1/2(2Z+5)

4z-2z x (-2z+8) = 2z + 5/2

2z x (-2z+8) = (4z+5)/2

z = 11/4
