5. 7 x (6 + n) = (7 x 6) + (7 × (-8))​

Penjelasan dengan langkah-langkah:

______________________________

[tex]\sf 7 \times (6 + n) = (7 \times 6) + (7 \times (-8))[/tex]

[tex]\sf 42 + 7n = 42 + (-56)[/tex]

[tex]\sf 42 + 7n = 42 - 56[/tex]

[tex]\sf 7n = 42 - 56 - 42[/tex]

[tex]\sf 7n = - 56[/tex]

[tex]\sf n = - 56/7[/tex]

[tex]\sf n = - 8[/tex]
