Question

Which option shows 5y – 8x = 7( x +y) – 9 expressed in the form of ax + by + c = 0 ? *

Answer 1

Answer:

answer for the given problem is given

Answer 2

SOLUTION

COMPLETE QUESTION

The equation 5y- 8x = 7(x + y) - 9 when expressed

in the form ax + by + c = 0 gives :

• 15x - 2y - 9 = 0

• 15x + 2y - 9 = 0

• - x + 6y - 9 = 0

• -x + 6y + 9 = 0

EVALUATION

Here the given equation is

$\sf{5y - 8x = 7(x + y) - 9}$

We know simply the equation and express it in the form ax + by + c = 0

$\sf{5y - 8x = 7(x + y) - 9}$

$\sf{ \implies \: 5y - 8x = 7x +7 y - 9}$

$\sf{ \implies \: 5y - 8x - 7x - 7 y + 9 = 0}$

$\sf{ \implies \: - 15x - 2y + 9 = 0}$

$\sf{ \implies \: 15x + 2y - 9 = 0}$

Which is of the form ax + by + c = 0

Where a = 15 , b = 2 , c = - 9

FINAL ANSWER

Hence the correct option is 15x + 2y - 9 = 0
