Question

Which system of equations has no solution?
5 x + 5 y = 10 and 2 x + 2 y = 4
3 x minus 6 y = 4 and negative 4 x + 8 y = 7
6 x + 2 y = 6 and 7 x + 3 y = 9
3 x minus 4 y = 16 and 2 x + 3 y = 5

Answer 1

5x+5 is the system to the equation.

Answer 2

The equation which has no solutions is 5 x + 5 y = 10 and 2 x + 2 y = 4

What is equation?

An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

As,

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

a1= 5, b1= 5, c1 = -10

a2= 2, b2= 2, c2 = -4

Now, a1/ a2 = 5/2

b1/ b2= 5/2

c1/ c2= -10/-4 = 5/2

Hence, a1/a2= b1/b2= c1/c2

So, the pair of equation has no solution.
