Question

⅘+1 ⅖=⅖x-2⅗
¼-⅓x=4 ¼-3x
2 ⅖x+3 2/15 =⅕x +2 ⅓
5,6+0,6=0,3x-1,3​

Answer 1

4/5 + 7/5 = 2x/5 - 13/5
2x - 13 = 11
2x = 24 => x = 12

1/4 - x/3 = 17/4 - 3x
3 - 4x = 51 - 36x
32x = 48 => x = 3/2 = 1 întreg 1/2

12x/5 + 47/15 = x/5 + 7/3
36x + 47 = 3x + 35
33x = (-12) => x = (-12/33) = (-4/11)

6,2 + 1,3 = 0,3x
x = 7,5 : 0,3
x = 75 : 3 = 25
