Answer:
infinite solutions
Step-by-step 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
