Question

Tell Whether each equation is true or false. Explain.

-------------------------------------------------------

31. x+1=x
32. 3+x=1+2+x
33. 98n = (100 - 2) n
34. 8+x=x+8

Answer 1

31. False

32. True

33. True

34. True

Explanation:

31. False ==> x=x, so if you add 1 to one side, you have to add one to the other side. Hence, x+1
`\\eq`x

32. True ==> 3=1+2. Hence, 3+x=1+2+x

33. True:

98n=(100 - 2)n

98*n=(100 - 2)*n

98*n=98*n √

34. True ==> 8+x=x+8 according to Symmetric Property of Equality
