Question

Hải giúp e mn ơi ào 9 câu d

Answer 1

d: \(\Leftrightarrow\left(9-8\right)x+36=16\cdot3=48\)

=>x=48-36

=>x=12

Answer 2

`=> (3^2 - 2^3)x + 3^2 . 2^2 = 4^2 xx 3`.

`=> x + 36 = 48`.

`=> x = 12`

Answer 3

`<=> (9 - 8)x + 36 = 16 . 3 = 48`

`=> x = 48 - 36`

`=> x = 12`

Answer 4

\(9)\\ a,\\ 3^2\left(x+4\right)-5^2=5\cdot22\\ 9\left(x+4\right)-25=110\\ 9\left(x+4\right)=110+25\\ 9\left(x+4\right)=135\\ x+4=135:9\\ x=15\)

~~~~~~~~~~~~~~~~

\(d,\\ \left(3^2\cdot2^3\right)x+3^2\cdot2^2=4^2\cdot3\\ \left(9\cdot8\right)x+9\cdot4=16\cdot3\\ 72x+36=48\\ 72x=48-36\\ 72x=12\\ x=\dfrac{12}{72}=\dfrac{1}{6}\)
