Answer:
(-3,3)
Step-by-step explanation:
3x=36-15y and 11x =-78+15y
We move all x and y terms to the left hand side of the equation , so that we can apply elimination method
3x=36-15y , Add 15 y on both sides , 3x + 15y = 36
11x =-78+15y, subtract 15y on both sides, 11x -15y = -78
Now we add both equations
3x + 15y = 36
11x -15y = -78
------------------------
14x = -42
divide both sides by 14
x= -3
Now Plug in -3 for x in any one of the given equation
3x=36-15y
3(-3) = 36 - 15y
-9 = 36 - 15y
Subtract 36 on both sides
-45 = -15y
Divide both sides by -15
So y= 3

Answer:
her mother drives 142 miles more than her brother.
Step-by-step explanation:
227 + 337 = 564 miles in total driven
¼ of 564 miles = 136 miles (what her brother drives of the 564 miles)
564 - 136 = 428 left
her mother drives 428-150 miles from Wednesday = 278
278-136=142
