Question

Find the sum of the coefficients of x and y of 7x - 3y + 8 = 0.​

Answer 1

$\large\sf\underline{Given}$

• $\sf\:7x - 3y + 8 = 0.$

$\large\sf\underline{To \:find}$

• $\sf\:Sum\:of \:the \:coefficients\: of\: x \:and\: y\:$

$\large\sf\underline{Solution}$

In the expression $\sf\:7x - 3y + 8 = 0.$

$\tt\pink{Coefficient\:of\:x=7}$

$\tt\pink{Coefficient\:of\:y=(-3)}$

$\sf\:Sum\:of\:the\:coefficient$

$\sf⟹\:7+(-3)$

$\sf⟹\:7-3$

$\tt\purple{⟹\:4}$

Answer 2

Step-by-step explanation:

7x - 3y + 8 = 0______( 1 )

7x - 3y = -8 ______( 2 )

7x = -8 + 3y

x = -8 + 3y ÷ 7 _______( 3 )

x का मान समीकरण ( 2 ) में रखने पर

7{ -8 + 3y ÷ 7 } -3y = -8

-56 + 21y - 3y = -56

18y = -56 + 56

y =0 ÷ 18

y = 0

y का मान समीकरण ( 3 ) में रखने पर

x = -8 + 3 × 0

x = -8 + 0

x = -8
