Question

tìm x

a, (x : 1,08) – 0,6 = 1,8       d, 12 – x = 37,6 : 4         h, x – 8,7 =12,5 x 5

b, x x 4 =37,6                     f, x : 4,8 – 1,6 = 15,9      

c, x : 4,8 = 15 + 2,4           g, x + 5,84 = 9,16

Answer 1

a: =>x:1.08=2,4

hay x=2,592

b: =>x=37,6:4=9,4

c: =>x:4,8=17,4

hay x=83,52

d: =>12-x=9,4

hay x=2,6

Answer 2

\(a,\left(x:1,08\right)-0,6=1,8\\ \Rightarrow x:1,08=2,4\\ \Rightarrow x=2,592\\ b,x\times4=37,6\\ \Rightarrow x=9,4\\ c,x:4,8=15+2,4\\ \Rightarrow x:4,8=17,4\\ \Rightarrow x=83,52\\ d,12-x=37,6:4\\ \Rightarrow12-x=9,4\\ \Rightarrow x=2,6\\ g,x+5,84=9,16\\ \Rightarrow x=3,32\\ h,x-8,7=12,5\times5\\ \Rightarrow x-8,7=62,5\\ \Rightarrow x=71,2\)
