Question

One equation in a system of equations is y=2x+10. Which equation below would have to be the second equation so that the system has infinitely many solutions?

Answer 1

Simplify Option D

• y=2(x+5)
• y=2x+2(5)
• y=2x+10

As everything is same

i.e

• A1/A2=B1/B2=C1/C2

Hence infinitely many solutions are present

Answer 2

D

Explanation:

y = 2x + 10 is the same thing as y = 2(x + 5) because 2 x x = 2x and 2 x 5 = 10
