y=4x-6.....(1)

5x+3y=1....(2)

substitute y=4x-6 into equation 2

5x+3(4x-6)=1

5x+12x-18=1

17x=19

x=1.12

substitute x=1.12 into equation 1

y=4(1.12)-6

y=4.48-6

y=-1.52

x=1.12,y=1.52

Answer:

Grades to be scored in 3rd exam = 88

Step-by-step explanation:

Given that average of 3 numbers is 85.

First two numbers are 81 and 86.

To find:

3rd number so that average is 85

Solution:

Let the third number = $x$

Formula for average is:

$Average = \dfrac{Sum\ of\ numbers}{Total\ count\ of\ numbers}$

Here, sum of numbers = $81+86+x =167+x$

Total count of numbers = 3

$85 = \dfrac{167+x}{3}\\\Rightarrow x=255-167\\\Rightarrow \bold{x=88}$

Grades to be scored in 3rd exam = 88
