Respuesta :
Answer :
- 3.8
- 0.4
- -8
- 1.53
Explaination :
1. Solve the equation x + 7.4 = 11.2
>> x + 7.4 = 11.2
>> x = 11.2 - 7.4
>> x = 3.8
2. Solve the equation : 9x = 4
>> 9x = 4
>> x = 4 / 9
>> x = 0.4
3. Solve the equation : -6x = 48
>> -6x = 48
>> -x = 48 / 6
>> -x = 24 / 3
>> -x = 8
>> x = -8
4. Solve the equation: 13x = −20
>> 13x = −20
>> x = -20 / 13
>> x = -1.53
1. Solve the equation: x + 7.4 = 11.2
[tex]x + 7.4 = 11.2 \\ \\ x = 11.2 - 7.4 \\ \\ x = 3.8[/tex]
3. Solve the equation: -6x = 48
[tex] - 6x = 48 \\ \\ x = \frac{ - 48}{ 6} \\ \\ x = - 8[/tex]
4. Solve the equation: 13x = −20
[tex]13x = 20 \\ \\ x = \frac{20}{13} \\ \\ x = 1.5[/tex]
2. Solve the equation: 9x = 4[tex]9x = 4 \\ \\ x = \frac{4}{9}
\\ \\x = 0.4 [/tex]
