Answer:
x = 4
Step-by-step explanation:
Given the 2 equations
2x - y = 11 → (1)
x + 3y = - 5 → (2)
Multiply (1) by 3 and add to (2) to eliminate the y- term
6x - 3y = 33 → (3)
Add (2) and (3) term by term to eliminate y, that is
7x = 28 ( divide both sides by 7 )
answer:
-4
-3x+8= 20
-8 -8
-3x = 12
÷-3. = ÷-3
x = -4
42.75 dollars more
57/4= 14.25
Gaurav has 14.25 dollars
57-14.25=42.75
therefore Deepa has 42.75 more dollars than Gaurav
