Answer:

x = -1/4

y = 1/2

Step-by-step explanation:

Given that:

y = -2x

y = 2x - 1​

Given equations can be written as:

y + 2x  =0 -------- eq1

y - 2x = 1​  -------- eq2

By adding both equations we get:

2y = 1

Dividing both sides by 2

y = 1/2

Putting value of y in eq1

1/2 + 2x = 0

2x = -1/2

Dividing both sides by 2

x = -1/4

i hope it will help you!
