you have $250 in market and bonds and $500 in stocks.
step-by-step explanation:
you split 1,000 into 4 quarter and take two of those quarters and there is what you invested in stocks and take one quarter for market and one quarter for bonds.
Cuz if so, then you just move the whole x term to the right side and divide all the terms on the right side by the coefficient of y for ex... 3) 4x+4y=16 4y=16-4x (or -4x+16) y=4-x or -x+4
