Question

Help!!Срочно
1) |x|+3=5
2) |y|-2=1
3) |2x|+3=9
4) |5y|-4=6
5) 3\7+|4x|=1
6) 4+|3y|=7

Answer 1

1) |x| = 5-3
|x| = 2
x = -2 и x = 2

2) |y| = 1+2
|y| = 3
y = -3 и y = 3

3) |2x| = 9-3
|2x| = 6
2|x| = 6
|x| = 3
x = -3 и x = 3

4) |5y| = 6 + 4
|5y| = 10
5|y| = 10
|y| = 2
y = -2 и y = 2

5)  |4x| = 1 - 3/7
4|x| = 4/7
|x| = 1/7
x = -1/7 и x = 1/7

6) |3y| = 7-4
3|y| = 3
|y| = 1
y = -1 и y = 1
