Question

Find the solution of this system of equations -2x=2+y , -6x-y=-2

Answer 1

(1,-4) Sox=1 and y would be -4

Answer 2

x = 1 and y = -4

Explanation:

It is given that,

-2x = 2 + y

-2x - y = 2 ---(1)

-6x - y = -2 ----(2)

To find the solution of equations

Step 1: Subtract eq(2) from eq(1)

-2x - y = 2 ---(1)

-6x - y = -2 ----(2)

4x + 0 = 4

x = 4/4 = 1

Step 2: Substitute the value of x in eq (1)

-2x - y = 2 ---(1)

-2*1 - y = 2

-2 - y = 2

y = -2 - 2 = -4

Therefore x = 1 and y = -4
