759.78=(a+33.1)32.4 x 1/2 must multiply both sides by 2 to get rid of 1/2
2(759.78)=(a+33.1)32.4 multiply and distribute each side
1519.56=32.4a+1072.44 subt. 1072.44 from both sides
1519.56-1072.44=32.4a now subt on the left side
447.12=32.4a now you can divide by 32.4 on both sides to get a by itself
447.12/32.4=a divide
13.8yd= a this should be the length of a
