Question

3) 9×(6x-13)=153; 4) 3× (8x+51)=201;

Answer 1

$1) 9(6x-13)=153\54x-117=153\54x=270\boxed{x=5}$

$2) 3(8x+51)=201\24x+153=201\24x=48\boxed{x=2}$

Answer 2

3)
9*(6х-13)=153
54х-117=153
54х=153+117
54х=270
х=270/54
х=5
Ответ.х=5
4)3(8х+51)=201
24х+153=201
24х=201-153
24х=48
х=48/24
х=2
Ответ.х=2
