Question

30+y= -12

2p-9= 101

100m= -1000

-5t+17= -13

24= 3z-12

169- 15k= -56

Answer 1

30+y= -12
y= -12-30
y= -42

2p-9=101
2p=101+9
2p= 110
p=110÷2
p= 55

100m= -1000
m= -1000÷100
m= -10

-5t+17= -13
-5t= -13-17
-5t= -30
t= -30÷5
t=6

24=3z-12
-3z= -12-24
-3z= -36
z= -36÷(-3)
z= 12

169-15k= -56
-15k= -56-169
-15k= -225
k= -225÷5
k= 15
