Question

Solve this system of equations:

Answer 1

Answer:

y=-3 x=1 (1,-3)

Step-by-step explanation:

y=x-4

y=6x-9

y+4=x

y+9=6x

difference = 5

x+5=6x

x=1

y=-3

1,-3

Answer 2

Answer:

x = 1

y = -3

Step-by-step explanation:

here's the solution,

=》y = x - 4

=》y = 6x - 9

in the given expressions , we have different values of y , so by equating values of y we get ,

=》x - 4 = 6x - 9

=》6x - x = -4 + 9

=》5x = 5

=》x = 1 ( by dividing both sides by 5 )

now, plugging the value of x as 1

=》x - 4 = y

=》1 - 4 = y

=》y = -3
