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
