Cody said b/-3 +12= 23 Solve for b.
b/-3+12=23
multiply althrough by -3 gives:
b - 36 = -69
make b the subject
=> b = -69 + 36
=> b = -33.

Cody:
b/-3 +12= 23 Solve for b

There are often lots of ways to solve equations
it may have been a bit easier to -12 from both sides first.
And then multiply both sides by -3
