Question

express 4x-y/3=7in the form ax+by+c=0

Answer 1

4x-y/3 = 7
4x-y = 21
4x - y - 21 = 0
-(-4x + y + 21) = 0
∴, ax + by + c = 0

Answer 2

$\color{red} \huge{\underline{\underline{\mathfrak{Answer}}} }$

$\frac{(4x - y)}{3} = 7$

★ By Cross Multiplication :-

$4x - y \: = 7 \times 3$

$4x - y \: = 7 \times 3$

$4x - y = 21$

$4x - y - 21 = 0$

$- ( - 4x - y - 21) \: = 0$

$⛬, \: ax \: + by \: + \: c \: = 0 \:$
