Explanation:

Answer 2

infinite solutions

Explanation:

2x + y = 5

3y = 15 – 6x

Solve the first equation for y

2x+y = 5

Subtract 2x on both sides

y = -2x + 5

Now we plug in y in second equation

3y = 15 - 6x

3(-2x+5) = 15 - 6x

-6x + 15 = 15 - 6x

We add 6x and subtract 15 on both sides

0 =0

We got 0=0, that is true but no x terms

So , there are infinite number of solutions
