Question

помогите решите уровнение
1. 1.32 Х + 4 = 10 3/5
2. 7/12 Х - 0.5 = 1.25

Answer 1

1,32x+4=10 3/5
1.32x+4= 10 6/10
1.32x+4=10.6
1.32x=10.6-4
1.32x=6.6
x=1.32/6.6
x=5

7/12x-0.5=1.25
7/12x-1/2=125/100
7/12x-1/2=1 25/100
7/12x-1/2=1 1/4
7/12x=5/4+1/2
7/12x=5/4+2/4
7/12x=7/4
x=7/12/7/4
x=7*4/7*12
x=1/3
