Question

ecuaciones 100m= -1000

-5t+17=-13

24=3z-12

169-15k=-56

Answer 1

100m= -1000
m = -1000/100 
m = - 10 


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


24=3z-12
24+12 = 3z
36 = 3z
36/3 = z
12 = t

169-15k=-56
169+56 = 15k
225 = 15k
225/15 = k
15 = k

Answer 2

m es -10
t es 6
k es 15
z es 12
