Need help quick! Will give brainliest to first right answer. Which system of equations has no solution?
O 5x+5y = 10 and 2x+2y=4
O 3x-6y = 4 and - 4x+8y=7
O 6x+2y = 6 and 7x+3y=9
O 3x-4y = 16 and 2x+3y = 5

the first one  or the last one

Step-by-step explanation:

5x+5y = 10 and 2x+2y=4

0 = 0

3x-6y = 4 and - 4x+8y=7

0 = 37 / 3

6x+2y = 6 and 7x+3y=9

0 = 3

3x-4y = 16 and 2x+3y = 5

x=4 and y=−1

x/7.50 = 15

x= 7.50 / 15 divide
