Let the first number be x and the second number be x+15.

According to the question,

x+x+15=95

2x=80

x=40

Hence, the first number is 40 and the second number is 55.

2x−3y=13...(1)

7x−2y=20....(2)

Let us use the elimination method to the given system of equations.

Multiply (1) by 2 and (2) by 3. And subtract both the equations.

−17x=−344x−6y=2621x−6y=60−+−

x=−14−34=+2

Substitute the value of x in equation (1), we have

y=−3

Hence x=2 and y=−3

Answer 2

Answer:

Answer

let total marks =x

Rachael scored marks=0.47x

0.47x=94

x=

0.47

94

x=200

Thus total marks will be 200
