which ordered pair (x,y) is a solution to the equation 3x+2y=11?

A. (-2,5)
B. (5,2)
C.(5,-2)
D.(-5,-2)
E.(-5,2)

1 answer

To determine which ordered pair \((x,y)\) is a solution to the equation \(3x + 2y = 11\), we can substitute each pair into the equation and see if it satisfies it.

Let's check each option:

A. \((-2, 5)\): \[ 3(-2) + 2(5) = -6 + 10 = 4 \quad (\text{not a solution}) \]

B. \((5, 2)\): \[ 3(5) + 2(2) = 15 + 4 = 19 \quad (\text{not a solution}) \]

C. \((5, -2)\): \[ 3(5) + 2(-2) = 15 - 4 = 11 \quad (\text{is a solution}) \]

D. \((-5, -2)\): \[ 3(-5) + 2(-2) = -15 - 4 = -19 \quad (\text{not a solution}) \]

E. \((-5, 2)\): \[ 3(-5) + 2(2) = -15 + 4 = -11 \quad (\text{not a solution}) \]

The only ordered pair that satisfies the equation \(3x + 2y = 11\) is option C: (5, -2).
