Which equation is modeled below? X 1 = X X 1 1
1

O -x + 1 = 2x + 3

O x + (-1) = 2x + 3

O x + (-1) = 3x + 2

O -2x = 2x + 3

-x + 1 = 2x + 3

The red x constitutes negative and yellow box means +1. Similarly two green boxes means 2x and three yellow box means +3.

Hope this helps :)

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
