Question

thanks u both but I want the check part please please help me​

Answer 1

Checking the solution

$\frac{5z - 11}{3z + 7} = - 2 \\ \\ putting \: z = \frac{ - 3}{11} \\ \\ \frac{5 \times \frac{ - 3}{11} - 11}{3 \times \frac{ - 3}{11} + 7 } \\ \\ \frac{ \frac{ - 15}{11} - 11 }{ \frac{ - 9}{11} + 7} \\ \\ \frac{ \frac{ - 15 - 121}{11} }{ \frac{ - 9 + 77}{11} } \\ \\ \frac{ \frac{ - 136}{11} }{ \frac{ 68}{11} } \\ \\ \frac{ - 136}{11} \times \frac{11}{68} \\ \\ - 2$

Hence, the answer is correct.
