10a+35b=0; 21a-35b=217 ...associative property of addition
31a = 217 .............addition property of equality
a = 7 .....................division property of equality
2(7) +7b = 0 --------------substitution property of equality
14+7b = 0 -----------------mulplication property of equality
7b = -14 --------------subtraction property of equality
b = -2 ----------------simplify
