Equivalent equation
Which equation, when solved, results in a different value of x than the other three?
A. −87x−43=20
Negative 7/8 x minus three-fourths = 20
B. 43+87x=−20
Three-fourths + 7/8 x = negative 20
C. −781x−3/4=20
Negative 7 ( 1/8 ) x minus three-fourths = 20
D. −87(−78x)−43=20(−78)
Negative 7/8 (Negative 8/7 ) x minus three-fourths = 20 (Negative 8/7 )
