Решить уравнения:8(11-3/4z)=16z-44 2(3-x/3)=5+x

Answer 1

8(11-3/4z)=16Z-44
88-24|4z=16z-44
6z-16z+88+44=0
6z-16z+132=0
-10z=-132
z=13/2

Comments

2(3-х/3)=5+х
6-2х/3=5+х
6-5+2х/3+х=0
1+3х/3=0
3х/3=-1
х=-1

Answer 2

88 - 24/4z = 16z - 44
88 - 6z = 16z - 44
132 = 22z
z = 132 / 22
z = 6;
6 - 2x/3 = 5 + x
6 - 5 = x + 2x/3
1 = 5/3*x
x = 3/5
