simplify the expression

(9m - 3) - (2m + 12)

1 answer

To simplify the expression \((9m - 3) - (2m + 12)\), follow these steps:

  1. Distribute the negative sign across the second parentheses: \[ 9m - 3 - 2m - 12 \]

  2. Combine like terms:

    • Combine the \(m\) terms: \(9m - 2m = 7m\)
    • Combine the constant terms: \(-3 - 12 = -15\)

Putting it all together, we get: \[ 7m - 15 \]

So, the simplified expression is: \[ \boxed{7m - 15} \]
