how do I solve for b?
multiply both sides by 3
9(ab-5) = b
distribute 9
9ab - 45 = b
subtract b, add 45 to both sides
9ab - b = 45
Factor out b
b(9a - 1) = 45
divide both sides by (9a-1)
b =
:
how do I solve for f? 2f-3=9h-fg
Add fg to both sides
2f + fg - 3 = 9h
Add 3 to both side
2f + fg = 9h + 3
Factor out f
f(2+g) = 9h + 3
Divide both sides by (2+g)
f =
