Question

Solve the following system:
y = 5x
3x + 2y = 52

Your answer:​

Answer 1

• 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.
