1. No answer ( may be due to incorrect question)
2. x = -3
y = 4
3. x= 4
y = 2
4.x = -63/40
y= -19/20
Step 1
Multiply equation 1 by the coefficient of x in equation 2
Multiply equation 2 by the coefficient of x I'm equation 1
(after completing this step you will derive equation 3 and 4 )
Step 2
Subtract equation 4 from equation 3
Step 3
Divide both sides of the equation by the coefficient of y
Step 4
substitute your value for y in equation 1 or 2
(after this you will derive the values of x)
Note : This method is for the Elimination of x

Answer:
The total distance cover by John is 15 min to reach his office .
Step-by-step explanation:
Given as ;
In the first 10 minutes , the distance cover is 1 miles every minutes
So, for 10 minutes , total distance cover by John = 10 × 1 = 10 miles
Again ,
John cover distance of 0.5 miles for every minutes , he travel for next 10 min
So, for next 10 min, total distance cover by John = 10 × 0.5 = 5 miles
So, The total distance cover by john = 10 miles + 5 miles = 15 miles
Hence The total distance cover by John is 15 min to reach his office . Answer
If you ate a third of the box and there ARE 16 left then you started with 48 originally
