Matematika 13 - 5n = -47
5a - 7 = 2a + 8
maka:
n + a × n - a =


#VeryEzz​

13 - 5n = -47
5a - 7 = 2a + 8
maka:
n + a × n - a =


#VeryEzz​

Penjelasan dengan langkah-langkah:

Untuk Nilai n

[tex] \sf13 - 5n = - 47[/tex]

[tex] \sf - 5n = - 47 - 13[/tex]

[tex] \sf - 5n = - 60[/tex]

[tex] \sf \: n = \frac{ - 60}{ - 5} [/tex]

[tex] \sf \: n = 12[/tex]

[tex] \\ \\ [/tex]

Untuk Nilai a

[tex] \sf5a - 7 = 2a + 8[/tex]

[tex] \sf5a - 2a = 8 + 7[/tex]

[tex] \sf3a = 15[/tex]

[tex] \sf \: a = \frac{15}{3} [/tex]

[tex] \sf \: a = 5[/tex]

[tex] \\ \\ [/tex]

[tex]{ \pmb{ \sf{nilai \to \: n + a \times n - a = .....}}}[/tex]

[tex] \\ [/tex]

= 12 + 5 × 12 - 5

= 12 + 5(12) - 5

= 12 + 60 - 5

= 72 - 5

[tex] \sf = \blue{67}[/tex]

Penjelasan dengan langkah-langkah:

13 - 5n = -47

-5n = -47 - 13

-5n =- 60

n = -60/-5

n = 12

5a - 7 = 2a + 8

5a - 2a = 8 + 7

3a = 15

a = 15/3

a = 5

maka

n + a × n - a

12 + 5 x 12 - 5

12 + 60 - 5

72 - 5

67

semoga membantu
