<u>Given Equation</u>:-

  • 5x+y=17 . . . . . . . . 1
  • x+y=3 . . . . . . . . . . 2

<u>To find</u> :

  • value of x
  • value of y

<u>Solution</u> :

<u>Let's start with equation 2</u>:-

x + y = 3

y = 3 - x

Put the value of y in Equation 1

  • 5x+y=17
  • 5x + (3 - x) = 17
  • 5x - x + 3 = 17
  • 4x + 3 = 17
  • 4x = 17 - 3
  • 4x = 14
  • x = 14/4
  • x = 7/2
  • x = <em>3.5</em>

<u>Now Let's find value of y</u><u>:</u>

put the value of x in equation 2:

y = 3 - x

y = 3 - 3.5

y = <em>0.5</em>
