Subtracting 2x and 7 from both quantities, we get quantity A equal to -11 and quantity B equal to 3x. Then, given that x > -3, quantity B is at least equal to 3*(-2.9999) = -8.99997, that is greater than -11. Thus quantity B is larger than quantity A.

We can solve this question using matching operations

Given: Quantity A: 2x - 4 Quantity B: 5x + 7

Subtract 2x from both quantities to get: Quantity A: -4 Quantity B: 3x + 7

Subtract 7 both quantities to get: Quantity A: -11 Quantity B: 3x

Divide both quantities by 3 to get: Quantity A: -11/3 Quantity B: x

Simplify to get: Quantity A: -3.666666... Quantity B: x

Since we're told that x > -3, we can be certain that x > -3.66666...

Answer: B
