Question

11 *(х-2)+3х=4*(х-8)-10
4х-(5х+8)=5-(12х-20)
24х=7*(2х-50)
-7*(х+2)+3=-4*(х-6)-2
4х+(7-2х)*3=7-(12х-4)
6х-(2х-4)=10-(5х-15)

Answer 1

1)11*(х-2)+3х=4*(х-8)-10
11х-22+3х=4х-32-10
14х-22=4х-42
14х-4х=-42+22
10х=-20   / :10
х= -2
2) 4х-(5х+8)=5-(12х-20)
4х-5х-8=5-12х+20
-1х-8=25-12х
-1х+12х=25+8
11х=33  / :11
х=3
3)24х= 7*(2х-50)
24х= 14х-350
24х-14х=-350
10х=-350   / :10
х= -35
4)-7*(х+2)+3=-4*(х-6)-2
-7х-14+3=-4х+24-2
-7х-11=-4х+22
-7х+4х=22+11
-3х=33      / :11
х=-11
5)4х+(7-2х)*3=7-(12х-4)
4х+21-6х=7-12х+4
-2х+21=11-12х
-2х+12х=11-21
10х=-10             / :10
х= -1
