Question

Point (m,2) lies on the line given by the equation 5x-y=20. find m​

Answer 1

`\qquad` ☀️
`\pink{\bf{ {m = \: \:4.4 }}}`

We are given –

• Point (m,2) lies on the line given by the equation 5x-y=20.

That means –

• x = m
• y = 2

Let's substitute the values of x & y in the given equation.

`\qquad`
`\pink{\twoheadrightarrow\bf 5x -y = 20 }`

`\qquad`
`\twoheadrightarrow\sf 5 * m - 2 =20`

`\qquad`
`\twoheadrightarrow\sf 5m =20+ 2`

`\qquad`
`\twoheadrightarrow\sf 5m = 22`

`\qquad`
`\twoheadrightarrow\sf m = (22)/(5)`

`\qquad`
`\twoheadrightarrow\sf m =\cancel{ (22)/(5) }`

`\qquad`
`\pink{\twoheadrightarrow\bf m = 4.4}`

• Henceforth, value of m will be 4.4.
