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

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
|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
Думаю так, смотри фото с решением ниже
