Answer 1

А) 3x-2=5
3x=5+2
x=7/3
x=2 1/3 (дробь)

б) 5x=2x+3=6

в) 8-3/5x=14
3/5x=-6
x=-10

Answer 2

Answer 3

а) 3x - 2 = 5 3x = 5 + 2 3x = 7 x = 7/3

б) 5x = 2x + 3 - 6 3x = -3 x = -1

в) 8 - (3/5)x = (14 3/5)x Multiplying both sides by 5 to eliminate the fraction: 40 - 3x = 73x Combining like terms: 40 = 76x Dividing both sides by 76: x = 5/19

Ответы: а) x = 7/3 б) x = -1 в) x = 5/19
