Question

tìm x :      152 : (4*X+6:2)*9=-4*-2  

Answer 1

\(152:\left(4x+6:2\right)\times9=\left(-4\right)\times\left(-2\right)\\ =>152:\left(4x+3\right)\times9=8\\ =>152:\left(4x+3\right)=\dfrac{8}{9}\\ =>4x+3=152:\dfrac{8}{9}\\ =>4x+3=152\times\dfrac{9}{8}\\ =>4x+3=171\\ =>4x=171-3\\ =>4x=168\\ =>x=168:4\\ =>x=42\)

Answer 2

152 : (4x +3) x 9 = 8 

(4x + 3) x 9 = 19 

4x + 3 = \(\dfrac{19}{9}\)

4x = \(\dfrac{-8}{9}\)

x = \(\dfrac{-2}{9}\)

Answer 3

152 : (4x +3 ) x 9 = 8

152 : (4x + 3) =\(\dfrac{8}{9}\)

4x + 3 = 171 

4x = 168 

x = 42
