You can put this solution on YOUR website!
1st: Multiply both sides by "4" to get:
9-2z=-20
Subtract "9" from both sides to get:
-2z=-29
Divide by "-2" to get:
z = 29/2
2nd: Multiply both sides by "5" to get:
4k=-8
Divide by "4" to get:
k = -2
3rd: Multiply both sides by "12" to get:
9-4z = 3
Subtract "9" from both sides to get:
-4z = -6
Divide thru by "-4" to get:
z = 3/2
