The second equation is solved for y, so substitute
8x+2 for y in the first equation:



Add 210-x to both sides:



Write 8 as 23



Remove the parentheses on the left by multiplying the
exponents:



Now we use the principle that 
if BP = BQ, then P = Q





Substitute in 






Answer: (x,y) = (1,512)
