  • y = 5x ............. (i)
  • 3x + 2y = 52 ............ (ii)

After putting the value of y into the eq. (ii) ,


\sf 3x + 2 * 5x = 52


\sf ⇒ \: 3x + 10x = 52


⇒ \sf13x = 52


\sf ⇒x = 4

After putting the value of x into the eq. (1)


\sf \: y = 5 * 4


⇒ \sf y = 20

Hence, the value of x is 4

& the value of y is 20.
