Which statement about the pair of equations is true? x = -2y + 300 3y = 800 - 4x a) the equation pair has no solutions. eliminate b) the equation pair has many solutions. c) the equation pair has exactly 1 solution. d) the equation pair has exactly 2 solutions.

C)The equation pair has exactly 1 solution.

Step-by-step explanation:

Rewrite the pair of equations

x + 2y = 300

4x + 3y = 800

Multiply the first equation by 4.

4x + 8y = 1200

4x + 3y = 800

Subtract the second equation from the first: 5y = 400 → y = 80 

Putting this value back in the original equation, x = -160 + 300 = 140

The equation pair has exactly 1 solution, x = 140, y = 80
