z góry dzięki a i daje naj.

Answer 1

1. x+75=75
x=75-75
x=0
2. 1⅔ + y=2 ³/₄
y=2¾-1⅔
y=11/4-5/3=33/12-20/12=13/12=1i1/12
y=1¹/₁₂
3. x-34=-35
x=-35+34=-1
x=-1
4. 3x=2x + ¹/₇
3x-2x=¹/₇
x=¹/₇

Answer 2

1. x+75=75
2. 1⅔ + y=2 ³/₄
3. x-34=-35
4. 3x=2x + ¹/₇

____

1. x+75=75 | -75
x=0

2. 1⅔ + y=2 ³/₄ |*12
20+12y=33 |-20
12y=13 |/12
y = 13/12

3.x-34=-35 |+34
x=-1

4. 3x=2x + ¹/₇ |-2x
x=1/7

Answer 3

1. x+75=75
x=75-75
x=0
2. 1 i 2/3 +y= 2 i 3/4
y= 2 i 3/4- 1 i 2/3
y=11/4-5/3
y=33/12-20/12
y=13/12
3.x-34=-35
x=-35+34
x=-1
4.3x=2x+1/7
3x-2x= 1/7
x=1/7
