DROPDOWN QUESTION

1 min • 1 pt

What is the first step when solving the system using the substitution method?

y=2x+4

2x+3y=20

Substitute ​ (a)   ​ for ​ (b)   in the 2nd equation to get ​ (c)  

2x+4

y

2x+3(2x+4)=20

Answer explanation

y=2x+4

2x+3y=20

Substitute 2x+4 for y in 2x+3y=20 to get:

2x+3(2x+4)=20

then you can solve that equation for x
