Question

Помогите решить
1. -6х-23=-9х-5
2. 2(4х-3)=5х+3
3. 6х+7=5(4х-1)-16
4. 15х-4(3х+5)=7(2х+5)
5. 5(3х-8)-3(2-5х)=4х-20
6. 2(х-23)+3(15-х)=-х+1

Answer 1

1. -6х-23=-9х-5
-6х+5х=23-5
-1х=18
х=-18
2. 2( 4х-3)=5х+3
8х-6=5х+3
8х-5х=9
3х=9
х=3
3. х=2
4. х=- 1 + 4/11
5. х= -6.5
6. х=3

Answer 2

1. 3x=18
x=18÷3
x=6
2.8х-6=5х+3
3х=9
х=3
3. 6х-20х=-5-7-16
-14х=-28
х=2
