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.

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

$\qquad$ $\twoheadrightarrow\sf 5 \times m - 2 =20$

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

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

$\qquad$ $\twoheadrightarrow\sf m = \dfrac{22}{5}$

$\qquad$ $\twoheadrightarrow\sf m =\cancel{ \dfrac{22}{5} }$

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

• Henceforth, value of m will be 4.4.
