How many solutions does this equation have?

5x-2y=10

15x-6=30

Given equation has a unique solution

Step-by-step explanation:

Consider

5x-2y=10 (1)

15x-6=30 (2)

form equation (2) firstly, we can calculate the value of x.

15x-6=30

15x=30+6

x=36/15

x=12/5

now by putting this value of "x" in (1)

5x-2y=10

5 (12/5) - 2y=10

12-2y=10

2y=12-10

2y=2

y=1
