Question

Amanda solves the equation 6x+9=57. She gets the answer x=0.5. Do you agree with Amanda? Explain your answer.

Answer 1

Answer:x=8

Step-by-step explanation:

6x+9=57

-9 -9

6x=48

6×/6=48/6

×=8

Answer 2

Answer:

Step-by-step explanation:

6x + 9 = 57

6x = 57 - 9

6x = 48

x = 48/6

x = 8

no...I dont agree with Amanda.

I arrived at x = 8.....and this can be confirmed by subbing in 8 for x back into the original equation.

6x + 9 = 57......x = 8

6(8) + 9 = 57

48 + 9 = 57

57 = 57 (correct)
