Which ordered pair in the form \((a, b)\) is a solution of this equation?

\[3a – 4b = 21\]

A. \((-3, -2)\)

B. \((0, 7)\)

C. \((7, 0)\)

D. \((-2, -3)\)

c - (7,0) because 3x7= 21 add 4x0 = 0 which then equals 21 :)

The ordered pair that is a solution to the equation 3 a − 4 b = 21 is ( 7 , 0 ) , as it satisfies the equation. Other options do not yield 21 when substituted into the equation.
