Answer:
2xy∧²√13xy
Step-by-step explanation:
The solution is x = 6 and y =1
Explanation :
In the substitution method we solve a system of equation by substituting the value of one variable from an equation to the another equation,
Given system of equations,
x-y = 5 ⇒ y = x - 5.......(1)
2x+y = 13.......(2)
Substitute the value of y from equation (1) to equation (2),
2x+x-5=13
3x-5=13
3x=18
x = 6
Again from equation (1),
y = 6 - 5 = 1
I can't see good the picture
8/v=6/v-3
8*(v-3)=6v
8v-8*3=6v
8v-24=6v
+24 +24
8v=6v+24
-6v -6v
2v=24
v=24/2
v=12 miles /hour
v2=12-3=9 miles /hour ( your friend)
am not sure pls double check
