Question

12.
3 (5z – 7) +2 (9z - 11)= 4 (8z - 7) - 111​

Answer 1

Answer: -96

Step by step explanation:

$\small\tt{3(5z - 7) + 2(9z - 11) = 4(8z - 7) - 111}$

Opening the brackets on both L. H. S and R.H.S

15z - 21 + 18z - 22 = 32z - 28 - 111

Simplifying the values :

33z - 43 = 32z - 139

33z - 32z = -139 + 43

z = -96

Hence, we get Final answer as -96.
