Question

525. Найдите значение 1) 2x 6; 2) 3x 12; 1 = х: 3) |5x| + 3 = 8; 4) 4x + 5 = 17; 5) |1,5x −2 = 4; 6) 7-6x = -5​

Answer 1

1) x= 6:2
x= 3
2) x= 12:3
x= 4
3) |5x| = 8 - 3
|5x| = 5

5x = 5
5x = -5

5x = 5
x = 5/5
x = 1

5x = -5
x = -5/5
x = -1

x = 1 и x = -1.
4) 4x = 17 - 5
4x = 12
x = 12/4
x = 3
5) 1.5x=4+2
x=6/1,5
x=4
6) -6x= -5-7
-6x=-12
x= -12/-6
x= 2.
