Question

12. 3 (5z - 7) +2 (92 - 11) = 4 (82-7) - 111​

Answer 1

Step-by-step explanation:

$\sf \huge \underline \blue{Answer:-}$

$\tt \implies \green{3(5z - 7) + 2(92 - 11) = 4(82 - 7) - 111}$

$\tt \implies \green{15z - 21 + 184 - 22 = 328 - 28 - 111}$

$\tt \implies \green{15z + 184 - 43 = 328 - 139}$

$\tt \implies \green{15z + 141 = 189}$

$\tt \implies \green{15z = 189 - 141}$

$\tt \implies \green{15z = 48}$

$\tt \implies \green{z = \frac{48}{15} }$

$\tt \implies \green{z = 3.2}$

Verification:

$\tt \implies \red{3(5 \times 3.2 - 7) + 2(92 - 11) = 4(82 - 7) - 111}$

$\tt \implies \red{27 + 162 = 300 - 111}$

$\tt \implies \red{189 = 189}$

Hence Verified !!
