You can put this solution on YOUR website!
3.7*b + 7 = 8.1*b -19.4
.
multiply by 10 to eliminate decimals
.
37b +70 = 81b - 194
.
subtract 70 from both sides
.
37b = 81b -194-70
.
37b = 81b -264
.
subtract 81b from both sides
.
37b -81b = -264
.
-44b = -264
.
divide both sides by -44
.
b = -264/-44
.
b = 6
.
Done.
