Question

Решите уравнения: 32x+(2-3x)=5

34*(x-2)=23

3x-12+x=4

2(x-3)+4=1

Answer 1

32x+(2-3x)=5
32x+2-3x=5
32x-3x+2=5
29x+2=5
29x=5-2
29x=3/:29
x=3/29
2)34*(x-2)=23
34x-68=23
34x-68=23
34x=23+68
34x=91/:34=x=91/34
3)3x-12+x=4
4x-12=4
4x=4-12
4x=-8/:4
x=-2
4)2(x-3)+4=1
2x-6+4=1
2x-2=1
2x=1+2
2x=3/:2
x=3/2=1.5

Answer 2

32х+(2-3х)=5
32х+2-3х=5
29х+2=5
29х=3
х=3/29
34*(х-2)=23
34х-68=23
34х=91
х=2 23/34
3х-12+х=4
4х-12=4
4х=16
х=4
2(х-3)+4=1
2х-6+4=1
2х-2=1
2х=3
х=1,5
