Question

Найдите корень уравнения:
1) 9(х+1)=х+15
2) (11х+14)-(5х-8)=25

Answer 1

1)9(х+1)=х+15
9х+9=х+15
9х-х=15-9
8х=6
х=6/8
х=0,75
2)(11х+14)-(5х-8)=25
11х+14-5х+8=25
6х=25-8-14
6х=3
х=3/6
х=0,5

Answer 2

1) 9(х+1)= х+15
9х+9=х+15
9х-х=15-9
8х=6
х=6/8
х=3/4
2)(11х+14)-(5х-8)=25
11х+14-5х+8=25
11х-5х=25-14-8
6х=3
х=3/6
х=1/2
