b) 7y - 8 = - y + 24
7y + y = 24 + 8
8y = 32 / : 8
y = 4
======
c)
- 8z + 5 = - z - 1
-8z + z = -1 - 5
- 7 z = - 6 / : ( -7)
z = 6/7
============
d)
-2m + 7 = m - 6
- 2m - m = - 6 - 7
-3m = - 13 / : ( - 3)
m = 13/3
============
b) 7y +y=24+8
8y=32
y=4
c)-8z+z =-5-1
-7z=-6
z=6/7
d) -2m -m =-6-7
-3m=-13
m=4 1/3
