[tex]b = \frac{7a}{5} \\ a + \frac{7a}{5} + 1 = a + \frac{7a}{5} \times \frac{5}{7a} + 10 \\ \frac{5a}{5} + \frac{7a}{5} + \frac{5}{5} = {35a}^{2} + \frac{35a}{35a} + \frac{350a}{35a} \\ {35a}^{2} + {49a}^{2} - 350a = 0 \\ 7a(7a - 50) = 0\\ 7a = 0 \\ a = 0 \\ 7a = 50 \\ a = \frac{50}{7} \\ b = 7 \times \frac{0}{5} \\ b = 0 \\ b = 7 \times \frac{50}{7} \\ b = 50[/tex]
