2x-1=y,2y+3=x

Step-by-step explanation:

Hope this helps ( Thanks!!! )  :D

 x=-1/3 and y=-5/3

Step-by-step explanation:

Solve 2x−1=y for y:

2x−1=y

2x−1+−y=y+−y(Add -y to both sides)

2x−y−1=0

2x−y−1+−2x=0+−2x(Add -2x to both sides)

−y−1=−2x

−y−1+1=−2x+1(Add 1 to both sides)

−y=−2x+1

-y/-1 =-2x+1/-1 (Divide both sides by -1)

y=2x−1

Substitute 2x−1 for y in 2y+3=x:

2y+3=x

2(2x−1)+3=x

4x+1=x(Simplify both sides of the equation)

4x+1+−x=x+−x(Add -x to both sides)

3x+1=0

3x+1+−1=0+−1(Add -1 to both sides)

3x=−1

3x/3=-1/3

x=-1/3

Substitute -1/3 for x in y=2x−1:

y=2x−1

y=2(-1/3)-1

y=-5/3 (Simplify both sides of the equation)
