2S = J
30J + 17S ≤ 500
Substitute 2S for J in the second equation and solve for S. Insert that value into the first equation to solve for J. Check by putting both values into the second equation.
Jess saved $500 working during the summer. He plans to buy school clothes with his money. He found jeans he liked for $30 per pair, including tax, and shirts for $17, including twice. If he buys exactly twice as many shirts as jeans, how many pairs of jeans can jess buy without exceeding $500
