substitute the equation x+1=y into the 2x-y=0  so you get 2x-(x+1)=0  once you do that out you get x=1  so you substitute x=1 back into one of the equations to find the y  (1) +1=y so the answer is b. (1,2)

Answer:

Option B is correct

(1, 2)

Step-by-step explanation:

Given the system of equation:

[tex]x+1 = y[/tex]               ......[1]

[tex]2x-y = 0[/tex]            ....[2]

We can rewrite [2] as:

2x = y                 ....[3]

Substitute this in [1] we have;

[tex]x+1 =2x[/tex]

⇒[tex]1 = x[/tex]

or

x = 1

Substitute in [3] we have;

[tex]y = 2(1) = 2[/tex]

∴Solution = (1, 2)

Therefore, the following ordered pairs is a solution of the given system of linear equations is, (1, 2)
