29.) \( 15 m=45 \) 36.) \( 2 m=124 \) 30.) \( 7 d=56 \) 37.) \( 14 r=42 \) 31.) \( 21 x=84 \) 38.) \( 29 t=77 \) 32.) \( 9 y=63 \) 39.) \( 9 x=143 \) 33.) \( \frac{2}{7} x=8 \) 40.) \( \frac{1}{2} v=10 \) 34.) \( \frac{3}{5} z=12 \) 41.) \( \frac{2}{3} c=8 \) 35.) \( \frac{4}{6} z=7^{1 / 3} \) 42.) \( \frac{3}{4} c=51 / 4 \)

To solve equations like these, remember that the goal is to isolate the variable. This often involves performing the same operation on both sides. For instance, if you're dealing with \( 15m = 45 \), divide both sides by 15 to find \( m \). This method allows you to systematically tackle each equation step-by-step. Don’t forget about checking your answers! After solving each equation, it’s vital to substitute your answer back into the original equation to ensure it holds true. This is a common mistake many make—assuming they got it right without verification! A simple plug-and-check can save you from error.
