Question

x+6y+1=0,2x+3y+8=0. Slove this equation ​

Answer 1

Answer:

x = -5 ;  y = 2/3

Step-by-step explanation:

Answer 2

Answer:

X = -5

Y= 2/3

explanation

x+6y+1=0. .........eq (1)

2x+3y+8=0. ..........eq(2)

from eq 1

x +6y+1= 0

x+6y = -1

x= -1-6y

x= -1(1+6y)

from eq 2

put value of x in eq 2

2[ -1(1+6y) ] +3y+8 = 0

-2Plug this in for variable x in equation [2]

[2] 2•(-6y-1) + 3y = -8

[2] - 9y = -6

// Solve equation [2] for the variable y

[2] 9y = 6

[2] y = 2/3

// By now we know this much :

x = -6y-1

y = 2/3

// Use the y value to solve for x

x = -6(2/3)-1 = -5
