Rozwiąż równania :
a) 3/8x - 1/4 = 2
b) 2/5x - 7 = 3
c) 5 - 7/8x - 3/4 = -1
d) 1i1/3x + 2/3 = 2
a) ⅜x=2¼
⅜x=⁹/₄ /*8
3x=18 //3
x=6
b) ⅖x=10 /*5
2x=50 //2
x=25
c) -⅞x=-5¼
-⅞x=-²¹/₄ /*8
-7x=-42 //(-7)
d) ⁴/₃x=⁴/₃ // ⁴/₃
x=1
Pomogłem? Podziękuj i daj NAJ :)
a) 3/8x -1/4 =2
3/8x = 2+1/4
3/8x = 2 i 1/4
3/8 x = 9/4 / * 8/3
x = 6
2/5x = 3+7
2/5x = 10 / *5/2
x = 25
-7/8 x = -1 - 5 + 3/4
-7/8x = -6 + 3/4
-7/8x = - 5 i 1/4
-7/8x = -21/4 / *(-8/7)
d) 1 i 1/3x + 2/3 = 2
1 i 1/3x = 2 -2/3
4/3x = 1 i 1/3
4/3x = 4/3 /:4/3
x = 1
myśle, że pomoglam , licze na naj. pozdrawiam gorąco :)
