Question

4z-3/4 -3=5z-7/3 -4z-1​

Answer 1

Answer:

$4z - \frac{3}{4} - 3 = 5z - \frac{7}{3} - 4z - 1 \\ \\ 4z - \frac{3}{4} - 3 = z - \frac{7}{3} - 1 \\ \\ 4z - z - 3 + 1 = - \frac{7}{3} + \frac{3}{4} \\ \\ 3z - 2 = \frac{ - 28 + 9}{12} \\ \\ 3z - 2 = \frac{ - 19}{12} \\ \\ 12(3z - 2) = - 19 \\ \\ 36z - 24 = - 19 \\ \\ 36z = - 19 + 24 \\ \\ 36z = 5 \\ \\ z = \frac{5}{36}$

Answer 2

$4z - \frac{3}{4} - 3 = 5z - \frac{7}{3} - 4z - 1 \\ = 4z - \frac{3 - 12}{4} = z - \frac{7 - 3}{3} \\ = 4z + \frac{9}{4} = z - \frac{4}{3} \\ = 4z - z = - \frac{4}{3} - \frac{9}{4} \\ = 3z = \frac{ - 16 - 27}{12} \\ = 3z = \frac{ - 43}{12} \\ = z = \frac{ - 43 \times 3}{12} \\ = z = - \frac{129}{12} = - 10.75$
