Find the solution of this system of equations. separate the x- and y-values with a comma. x - 4y = -22 x- y=-10 enter the correct answer. done

{-6,4}

Step-by-step explanation:

Given

x-4y=-22      Eqn 1

x-y=-10         Eqn 2

Subtracting both equations:

The left hand side of equation 2 will be subtracted from left hand side of eqn 1 and the right side of equation 2 will be subtracted from right hand side of eqn 1.

Putting y=4 in eqn 2

{x, y} = {-6, 4}

Step-by-step explanation:

It is given that,

x - 4y = -22    (1)

x -  y= -10   (2)

To ind the value of x and y

subtract eq(2) from eq(1)

x - 4y = -22    (1)

x -  y= -10   (2)

0  -3y = -12

3y = 12

y = 12/3 = 4

Substitute the value of y in eq (1)

x - 4y = -22    (1)

x - (4*4) = -22

x - 16 = -22

x = -22 +16 = -6

Therefore {x, y} = {-6, 4}
