#s = 7/8#

Explanation:

Given: #1/8 = s - 3/4#

The first is to add #3/4# to both sides so the variable #s# is isolated:

#1/8 + 3/4 = s#

To add the two fractions they must have the same denominator. The denominator #4# is a multiple of #8#, so multiply the #3/4# by #2/2 = 1#:

#1/8 + 3/4 *2/2= s#

#1/8 + 6/8 = s#

#7/8 = s#
