Determine whether the following system of equations has one solution, no solution, or an infinite number of solutions. Explain your reasoning.

2x - 4y = 10

7x - 9y = 12

A) 2x - 4y = 10

B) 7x - 9y = 12

Multiplying equation A by - 3.5

A) - 7x + 14y = - 35 then adding B

B) 7x - 9y = 12

5y = - 23

y = - 4.6

2x - 4*-4.6 = 10

2x + 18.4 = 10

2x = - 8.4

x = - 4.2

It has one solution (-4.2, - 4.6)
