Question

75:(x-18)=15^2

Answer 1

\(75:\left(x-18\right)=15^2\\ \Leftrightarrow75:\left(x-18\right)=225\\ \Leftrightarrow x-18=75:225\\ \Leftrightarrow x-18=\frac{1}{3}\\ \Leftrightarrow x=\frac{1}{3}+18\\ \Leftrightarrow x=\frac{55}{3}\)

Vậy pt có nghiệm là \(x=\frac{55}{3}\)

Answer 2

75:(x-18)=15²

⇔75: (x-18) =2 25

⇔x-18 = 75:225

⇔x-18= \(\frac{1}{3}\)

⇔x = \(\frac{1}{3}\)+ 18

⇔x= \(\frac{55}{3}\)

Vậy x = \(\frac{55}{3}\)

Answer 3

75 : (x - 18) = 15²

75: (x - 18) = 225

x - 18 = \(\frac{75}{225}\)

x - 18 = \(\frac{1}{3}\)

x = \(\frac{1}{3}+18\)

x = \(\frac{55}{3}\)

Vậy x = \(\frac{55}{3}\)

Answer 4

\(75\div(x-18)=15^2\)

\(75\div(x-18)=225\)

\(x-18=75\div225\)

\(x-18=\frac{1}{3}\)

\(x=\frac{55}{3}\)

\(Vậyx=\frac{55}{3}\)
