5 = 4х - 3 х
х = 5
2х - 35 = 34х - 12
2х - 34х = - 12 +35
2х - 34х =1ц 44х - 34х =1ц 14х
- 12 +35 =35 + [- 12] =610 + [ - 510] = 110
1ц 14x = 110 х =110 : 1ц14 = 110 :54=110 x 45=225 х =225
х = 5
2х - 35 = 34х - 12
2х - 34х = - 12 +35
2х - 34х =1ц 44х - 34х =1ц 14х
- 12 +35 =35 + [- 12] =610 + [ - 510] = 110
1ц 14x = 110 х =110 : 1ц14 = 110 :54=110 x 45=225 х =225
