Which equation shows the result of substituting and expression for y from the first equation into the second equation for the
given system?
ly=x+5
ly-2x=2
(5 – x) – 2x = 2
(x + 5) - 2x = 2
(x + 5) + 2x = 2
(x + 5)-2x = 0

(b) After substitution: the givens system is  (x + 5) -  2 x  =  2 .

Step-by-step explanation:

Here, the system of equations is:

y = x + 5

y - 2 x = 2

Now, substituting the value of y   = x + 5 in the second equation, we get

y - 2 x = 2

⇒   (x + 5) -  2 x  =  2

Hence, after substitution: the givens system is  (x + 5) -  2 x  =  2 .
