    13p = 2a + x 4p + a = x p = plums, a = apples, x = pears you need to find an equation with onle plums(p) and pears(x) by solving for a on the second equation: a = x - 4p and substituting the first equation: 13p = 2(x - 4p) + x 13p = 2x - 8p + x 13p = 3x - 8p 21p = 3x (21 plums = 3 pears, but the questions is plums to ONE pear, so solve for x) x = 7p 7 plums = 1 pear
