Question

aflati x din egalitatea [(1,84*x+1,4-2,3):2+1,25-8]÷0,2-2=8

Answer 1

[(1,84·x+1,4-2,3):2+1,25-8]:0,2=8-2=10
[(1,84·x+1,4-2,3):2+1,25-8]=10·0,2=2
(1,84·x+1,4-2,3):2+1,25)=2+8=10
1,84·x+1,4-2,3:2=10-1,25=8,75
1,83·x+1,4-2,3=8,75·2=17,5
1,84·x+1,4=17,5+2,3=19,8
1,84·x=19,8-1,4=18,4
x=18,4:1,84
x=10
