WILL GIVE BRAINLEIST NEED TO TURN IN BY 9 P.M. PLS HURRY SUPER EASYIdentify the equation that does not belong with the other three. Explain your reasoning. A. 6+x=9 B. 15=x+12 C. x+9=11 D. 7+x=10

Answer:C. x + 9 = 11Step-by-step explanation:We are trying to identify which of the equations does not match with the others. In this case, solve for x in each equation: Option A): 6 + x = 9Subtract 6 from both sides: 6 (-6) + x = 9 (-6)x = 9 - 6x = 3Option B): 15 = x + 12Subtract 12 from both sides: 15 (-12) = x + 12 (-12)15 - 12 =  xx = 3Option C): x + 9 = 11Subtract 9 from both sides: x + 9 (-9) = 11 (-9)x = 11 - 9x = 2Option D): 7 + x = 10Subtract 7 from both sides: x + 7 (-7) = 10 (-7)x = 10 - 7x = 3---------------------------------------------------------------------------------------------------------As you can tell, all the equations end with x = 3 as there answers except C. x+9=11, making (C) your answer.~
