Question

Решите уравнение: 1 ) x+ 7/12 = 3/4. 2) x- 1/6 = 1/9. 3) x- 3/5=3/8. 4) x+5/24 = 7/24. 5) y+2/7 =1/3. 6) x-1/6 =7/9. 7) y - 3/8 =5/32. 8) y+ 2/5 =1/2

Answer 1

1) x+7/12=3/4
x=3/4-7/12
x=1/6

2)x-1/6=1/9
x=1/9+1/6
x=5/18

3)x-3/5=3/8
x=3/5+3/8
x=39/40

4)x+5/24=7/24
x=7/24-5/24
x=1/12

5)y+2/7=1/3
y=1/3-2/7
y=1/21

6)x-1/6=7/9
x=7/9+1/6
x=17/18

7)y-3/8=5/32
y=3/8+5/32
y=17/32

8)y+2/5=1/2
y=1/2-2/5
y=1/10
