sure
8.4 =83.7(y+(-54.7) <--- postive times negative sign.Negative
8.4 =83.7 (y-54.7)<--- distribute
8.4=(83.7y- 4578.39)
4578.39+8.4 =83.7y <--find y
4586.79 =83.7y
54.8 =y

8.4=83.7(y-54.7)
y-54.7=8.4/83.7
y-54.7=0.10035842
y=0.10035842+54.7
y=54.8003584 or
y=54.8 or
y=55

8.4=83.7(y+(-54.7))
8.4 / 83.7 = y -54.7
y = (8.4 / 83.7) + 54.7
y = 54.8

8.4 = 83.7(y + (-54.7))
y + (-54.7)) = 8.4/83.7
y = 8.4/83.7 + 54.7
