How many solutions does this system have?
5x - y = 3
2y = 10x+2
one
two
an infinite number
no solution
!

Step-by-step explanation:

5x - y = 3(1)

2y = 10x+2(2)

Rearranging (2)

-10x + 2y = 2(3)

Multiply equation (1) by 2

10x - 2y = 6(4)

Adding (3) and (4)

-10x + 10x + 2y - 2y = 2 + 6

No solution since both x and y are eliminated.
