Question

4x +5y +2=0,3x+y+ 7=0.​

Answer 1

Step-by-step explanation:

4x + 5y + 2 = 0

3x + y + 7 = 0

Solution :-

4x + 5y + 2 = 0 --------(1)

3x + y + 7 = 0 ----------(2)

3x + y = - 7

y = - 3x - 7 ----------(3)

Putting the value of y in equation 1

4x + 5( - 3x - 7) + 2 = 0

4x - 15x - 35 + 2 = 0

- 11x - 33 = 0

- 11x = 33

x = 33/- 11

x = - 3 ------------(3)

now the putting the value of x in equation 3

y = - 3( - 3) - 7

y = 9 - 7

y = 2

now the value of x = - 3 and y = 2
