1) х + 3 = 6
2) 5х + 10 = 2х + 4 ?в виде равенства: число 56 в х раз больше числа 14;
ответ:14*4=46 в 4 раза число 56 больше 14.

какое из чисел 3; -2 является корнем уравнения:
1) х + 3 = 6
2) 5х + 10 = 2х + 4 ?
корень первого уравнения 3
корень второго уравнения-2

есть ли среди чисел -1; 1/2; 0 корень уравнения:

1) 3(х+2) = 4 + 2х

2) 5(х + 1) - 4х = 4 ?

УМОЛЯЮ

решаем 1) 3(х+2) = 4 + 2х
3х+6=4+2х
3х-2х =4-6
х=-2 не подходит
2) 5(х + 1) - 4х = 4
5х+5-4х=4
х=4-5
х=-1 а вот и подходящий корень
