Associative property of addition
Step-by-step explanation:
h = -9/10 & j = -7/2
Step-by-step explanation:
This what i get :
5h-j=-1
3j-5h=-6
5h-j=-1
-j=-5h-1
J= -5h/-1+ -1/-1
J= 5h +1
Now sub substitute second equation
3j-5h=-6
3(5h+1)-5h=-6
15h+3-5h=-6
15h-5h+3=-6
10h+3=-6
10h= -6-3
10h= -9
H=-9/10
5(-9/10)-j =-1
-4.5-j=-1
-j=-1+4.5
-j=3.5
J=3.5/-1
J= -7/2
