Question

А) 1,9х+3,34х-2,24х=30,66б)а) 1,9х+3,34х-2,24х=30,66б) 96,41х-88,24х+1,83х=0,0202в)4,25=+56,402х-4,652х=58,912г) 5,45х-4,568х-0,882х=0

Answer 1

1,9х+3,34х-2,24х=30,66
3х=30,66
х=30,66:3
х=10,22

96,41х-88,24х+1,83х=0,0202
10х=0,0202
х=0,0202:10
х=0,00202

4,25х+56,402х-4,652х=58,912
56х=58,912
х=58,912:56
х=1,052

5,45х-4,568х-0,882х=0
0х=0
х=любому числу наверное

Answer 2

A) 1.9x + 3.34x - 2.24x = 30.66 Combine like terms: 2x = 30.66 Divide by 2: x = 15.33

B) 1.9x + 3.34x - 2.24x = 30.66 Combine like terms: 2x = 30.66 Divide by 2: x = 15.33

C) 96.41x - 88.24x + 1.83x = 0.0202 Combine like terms: 10x = 0.0202 Divide by 10: x = 0.00202

D) 4.25 = 56.402x - 4.652x = 58.912 Combine like terms: 51.75 = 51.75x Divide by 51.75: x = 1

E) 5.45x - 4.568x - 0.882x = 0 Combine like terms: 0.0x = 0 This equation has infinitely many solutions since any value of x will satisfy the equation.
