Answer:

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

Explanation:

2y-2=4x

y=-x+4

----------

2y-2=4x implies 2(y-1)=2(2x), so y-1=2x.

(-x+4)-1=2x

-x+4-1=2x

-x+3=2x

3=2x-(-x)

3=2x+x

3=3x

x=3/3

x=1

y=-1+4=3

Answer: x=1,y=3

Step-by-step explanation:

Given,

y - 1 =2x

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

Again,

We have,

y = 2x + 1

Now replacing the value of y from (i)

2x + 1= -x +

or, 2x + x= 3

or,3x= 3

So x=1

Now,

y=2x +1

or, y=2×1+1

so y=
