Question

Which equation, when solved, results in a different value of x than the other three? Negative StartFraction 7 over 8 EndFraction x minus three-fourths = 20 Three-fourths + StartFraction 7 over 8 EndFraction x = negative 20 Negative 7 (StartFraction 1 over 8 EndFraction) x minus three-fourths = 20 Negative StartFraction 7 over 8 EndFraction (Negative StartFraction 8 over 7 EndFraction) x minus three-fourths = 20 (Negative StartFraction 8 over 7 EndFraction)

Negative StartFraction 7 over 8 EndFraction (Negative StartFraction 8 over 7 EndFraction) x minus three-fourths = 20 (Negative StartFraction 8 over 7 EndFraction)

Step-by-step explanation:

All of the equations are equivalent to …

-7/8x -3/4 = 20

except the last one, which is …

-7/8(-8/7)x -3/4 = 20(-8/7)

To make it equivalent, the -3/4 term would also need to be multiplied by (-8/7).
