Question

Y=3x+4

Y=-3x-4

A.) Exactly one solution

B.)No solution

C.)Infinitely many solutions

Answer 1

Hi there! The answer is A.


`y = 3x + 4 \\ y = - 3x - 4`

Combine the data

`3x + 4 = - 3x - 4`

Add 3x to both sides.

`6x + 4 = - 4`

Subtract 4 from both sides.

`6x = - 8`

Divide by 6.

`x = ( - 8)/(6) = - 1 (1)/(3)`

The answer is A. exactly 1 solution.
