  1. Add 33.22 to solve ww: To solve for ww in the first equation, add 33.22 to both sides.\newlinew3.2+3.2=5.6+3.2w - 3.2 + 3.2 = 5.6 + 3.2\newlinew=8.8w = 8.8
  2. Subtract 48.5548.55 for kk: For the second equation, subtract 48.5548.55 from both sides to solve for kk.\newline48.55+k48.55=61.7748.5548.55 + k - 48.55 = 61.77 - 48.55\newlinek=13.22k = 13.22
  3. Divide by 11.66 for yy: To find yy in the third equation, divide both sides by 11.66.\newline9.6=1.6y9.6 = 1.6y\newliney=9.61.6y = \frac{9.6}{1.6}\newliney=6y = 6
  4. Subtract 2(45)2\left(\frac{4}{5}\right) for mm: For the fourth equation, subtract 2(45)2\left(\frac{4}{5}\right) from both sides to solve for mm. \newline79=2(45)+m\frac{7}{9} = 2\left(\frac{4}{5}\right) + m\newlinem=792(45)m = \frac{7}{9} - 2\left(\frac{4}{5}\right)\newlinem=79245m = \frac{7}{9} - \frac{24}{5}\newlinem=3521645m = \frac{35 - 216}{45}\newlinem=18145m = -\frac{181}{45}\newlinem=4.022222m = -4.022222\ldots
