Step-by-step explanation:

PLEASE ANSWER ASAP!!!!! DONT NEED much explanation How many solutions does this system have? (photo below)

Tema [17]

Answer:

infinite solutions

Step-by-step explanation:

Multiply the first equation by 2

2(3x-5y) = 2*15

6x - 10y = 30

This is the same as the second equation

They are the same line

This means there are infinite solutions
