Answer:
Option b) is correct
3x+4(2x+4)=17 Substitute (2x+4) for y in the second equation
Step-by-step explanation:
Given Equations are
[tex]y=2x+4\hfill (1)[/tex] and [tex]3x+4y=17\hfill (2)[/tex]
To solve the given equations we have to find the value of
x and y values.
Here y value is given so that we can substitute y=3x+4 value in second equation
ie., Substitute equation (1) in (2) equation we can easily get x value.
Therefore substitute (2x+4) for y in the second equation we get
3x+4(2x+4)=17
Option b) is correct
