To solve the equation \( 3m + 54 - \frac{3m}{4} = -2 \), we first need to combine like terms.
-
Start with the equation: \[ 3m + 54 - \frac{3m}{4} = -2 \]
-
To eliminate the fraction, let's express \( 3m \) with a common denominator. We can express \( 3m \) as \( \frac{12m}{4} \): \[ \frac{12m}{4} + 54 - \frac{3m}{4} = -2 \]
-
Combine the \( m \) terms: \[ \frac{12m - 3m}{4} + 54 = -2 \] \[ \frac{9m}{4} + 54 = -2 \]
-
Now, isolate the term with \( m \): \[ \frac{9m}{4} = -2 - 54 \] \[ \frac{9m}{4} = -56 \]
-
To eliminate the fraction, multiply both sides by 4: \[ 9m = -56 \times 4 \] \[ 9m = -224 \]
-
Divide both sides by 9 to solve for \( m \): \[ m = \frac{-224}{9} \]
Thus, the value for \( m \) that makes the equation true is: \[ m = \frac{-224}{9} \]
