Responses

−3.2x=0.64
and x4=−0.05
negative 3.2x equals 0.64 and Start Fraction x over 4 End Fraction equals negative 0.05

−34x=52
and 52x=−34
negative Start Fraction 3 over 4 End Fraction x equals Start Fraction 5 over 2 End Fraction and Start Fraction 5 over 2 End Fraction x equals negative Start Fraction 3 over 4 End Fraction

38x=1
and 13x=18
Start Fraction 3 over 8 End Fraction x equals 1 and Start Fraction 1 over 3 End Fraction x equals Start Fraction 1 over 8 End Fraction

x3.2=1.8
and 1.8x=3.2

Answer 1

The first pair.

−3.2x = 0.64 → x = 0.64/−3.2 = −0.2.
x/4 = −0.05 → x = −0.05·4 = −0.2.

Both give x = −0.2; the other pairs give different solutions.
