Question

3 X + Y + 1 is equal to zero 2 x minus 3 Y + 8 is equal to zero by substitution method​

Answer 1

Answer:

x = -1 and y = 2

Step-by-step explanation:

Given equation: 3x +y +1 =0 (equ.n -1)

2x - 3y +8=0 (equ.n-2)

Express equation -1 in terms of x:

y = -1 -3x (equ.n- 3 )

Substitute value of y in equation- 2 :

2x- 3(-1 - 3x) +8 =0

or, 2x +3 +9x + 8 =0

or, 2x +9x +3 + 8 =0

or, 11x + 11 =0

or, 11x = - 11

or, x = - 11 / 11

or, x = -1

Substitute value of x in equation -3 :

y = - 1 -3 ( - 1 ) = - 1 + 3 = 2
