5/8m-3/8=1/2m+7/8 how do you solve this. variables on both sides. step by step !

Combine like terms:  (5/8)m - (1/2)m = 7/8 + 3/8 = 10/8

                                        (1/8)m = 10/8

Now mult both sides by 8 to remove 8 from the denominators:

                                             m = 10

y = x + 95

y = 42 + 95

y=137 mm hg

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
