Question

y=1.9x-6
3y=5.7x-18
what conclusion can you make abot this problem?
-one solution
-ims
-two solutions

Answer 1

Substitute the first equation, y = 1.9x - 6 into the second one for y. 

3(1.9x - 6) = 5.7x - 18

Distribute the 3. 

5.7x - 18 = 5.7x - 18 

This means that there are infinite solutions, since the two equations are the exact same lines. 

Hope this helps!
