Question

5) 3/7+|4х|=1
6) 4+|3у|=7​

Answer 1

Ответ:

5) 3/7+|4x|

3/7+4×|x|=1

4×|x|=1-3/7

4×|x|=4/7

|x|=1/7

x= -1/7

x= 1/7

6) 4+|3y|=7

4+3×|y|=7

3×|y|=7-4

3×|y|=3

|y|=1

y=1

y= -1

Answer 2

$1)\\\frac{3}{7} + |4x| = 1\\\\\frac{3}{7} + 4 * | x | = 1\\\\4 * |x| = 1 - \frac{3}{7} \\\\4 * |x| = \frac{4}{7} \\\\| x | = \frac{1}{7} \\\\x = \frac{1}{7} \\x = -\frac{1}{7} \\\\OTBET: x_{1} = -\frac{1}{7} , x_{2} = \frac{1}{7} \\\\\\2)\\4 + |3y| = 7\\\\4 + 3 * |y| = 7\\\\3 * |y| = 7 - 4\\\\3 * |y| = 3\\\\|y| = 1\\\\y = 1\\y = -1\\\\OTBET: y_{1} = -1 , y_{2} = 1$
