Answer:

1 1/8

Step-by-step explanation:

x + 1 3/4 = 2 7/8  ( subtract 1 3/4 to isolate x)

2 7/8 is the same as 23/8

1 3/4 is the same as 7/4

you have to have the same denominator to subtract the fractions so you multiply 7/4 by 2

this gets 23/8 - 14/8 ( you subtract 23-14)

you get 9/8 which is the same as 1 1/8
