Решите уравнение.(x+240)*3=1260;x+(240*3)=1260;x+240=1260*3

Question

Решите уравнение.
(x+240)*3=1260;x+(240*3)=1260;x+240=1260*3

Answer 1

(x+240)*3=1260
3х+720=1260
3х=1260-720
3х=540
х=540:3
х=180
или
(x+240)*3=1260
х+240=1260:3
х+240=420
х=420-240
х=180

x+(240*3)=1260
х+720=1260
х=1260-720
х=540

x+240=1260*3
х+240=3780
х=3780-240
х=3540
