given the equation ax + b = 9x + 21 which set of values for a and b would result in an equation with infinity many solutions
a = 3,b = 7
a = 9, b = 9
a = 9, b = -21
a = 9, b = 21

Respuesta :

Answer:

  • D. a = 9, b = 21

Step-by-step explanation:

Given the equation

  • ax + b = 9x + 21

For the equation to have infinitely many solutions, both sides of the equation should be same.

  • a = 9 and b = 21 will make both sides equal

Correct option is D
