Question

(17x-25):2mũ3+65=9mũ2

Answer 1

(17x - 25) : 2³ + 65 = 9²

(17x - 25) : 8 + 65 = 81

(17x - 25) : 8 = 81 - 65

(17x - 25) : 8 = 16

17x - 25 = 16 x 8

17x - 25 = 128

17x = 128 + 25

17x = 153

x = 153 : 17

x = 9.

Answer 2

\(\left(17x-25\right):2^3+65=9^2\)

\(=>\left(17x-25\right):8+65=81\)

\(=>\left(17x-25\right):8=81-65\)

\(=>\left(17x-25\right):8=16\)

\(=>17x-25=16.8\)

\(=>17x-25=128\)

\(=>17x=128+25\)

\(=>17x=153\)

\(=>x=153:17\)

\(=>x=9\)
