This is your answer bro

Answer 2

Answer:

$c) \: \: \frac{7a + 4}{a + 2} = \frac{ - 4}{3} \\ cross \: multiplication \\ 3 \times (7a + 4) = - 4 \times (a + 2) \\ = 21a + 12 = - 4a - 8 \\ = 21a + 4a = - 8 - 12 \\ = 25a = - 20 \\ = a = \frac{ - 20}{25} = \frac{ - 4}{5} = - 0.8 \: \: ans$

$d) \\ \\ \frac{4x + 8}{5x + 8} = \frac{5}{6} \\ cross \: multiplication \\ 6 \times (4x + 8) = 5 \times (5x + 8) \\ = 24x + 48 = 25x + 40 \\ = 25x + 40 - 24x - 48 = 0 \\ = 25x - 24x - 48 + 40 = 0 \\ = x - 8 = 0 \\ = x = 8 \: \: ans$
