Question

chapter name - linear equation class 8 please solve this answer is -1
but I want step by step solution please help me​

Answer 1

Answer:

4z+7/9-3z=1/4

4(4z+7)=1(9-3z)

16z+28=9-3z

16z+3z=9-28

19z= -19

z= -19/19

z= -1

Answer 2

Step-by-step explanation:

$\sf : \implies \frac{4z + 7}{9 - 3z} = \frac{1}{4} \\ \sf : \implies \: 4(4z + 7) = 9 - 3z\\ \sf : \implies 16z + 28 = 9 - 3z\\ \sf : \implies \: 16z + 3z = 9 - 28\\ \sf : \implies 19z = -19\\ \sf : \implies z = \frac{19}{19} \\ \sf : \implies z = -1 ans.$
