Step-by-step explanation:
m+3=9
m=9-3=6
The second question I guess that it is solved like
2x+5=11
2x=11-5
2x=6
X=3
Or the other qusetion 5x-8=27
5x=19
X=19/5
I don't know the machine so sorry
B. 24x+27. You multiply everything out and add the x's
C/3 = 6 1/7
Multiply 3 to both sides:
C = 6 1/7 * 3
Convert 6 1/7 into an improper fraction:
C = 43/7 * 3
Multiply 3 to the numerator:
C = 129/7
Convert back into a mixed number:
C = 18 3/7
