Simplifying2b + -7c = 9
Solving2b + -7c = 9
Solving for variable 'b'.
Move all terms containing b to the left, all other terms to the right.
Add '7c' to each side of the equation.2b + -7c + 7c = 9 + 7c
Combine like terms: -7c + 7c = 02b + 0 = 9 + 7c2b = 9 + 7c
Divide each side by '2'.b = 4.5 + 3.5c
Simplifyingb = 4.5 + 3.5c
