The resulting values are -1 and -1/4
If three-fourths was subtracted from a number, and then 5 1/4 was added to the result, the equivalent expression will be:
x - 3/4 = -7 + 5 1/4
Solve to have the expression
x - 3/4 = -7 + 21/4
x - 3/4 = -7/4
x = -7/4 + 3/4
x = -4/4
x = -1
Hence the equivalent value and original number is -1
m + 2/3 = 1/2
m = 1/2 - 2/3
m = 3-4/6
m = -1/4
Hence the resulting values are -1 and -1/4
