6) 6n+ 3 = 3(-7n + 1)<br> what did you guys get for the answer?
Allushta [10]

Answer:

n=0

Step-by-step explanation:

Clear parenthesis w/ distribution:

3(-7n+1)=-21n+3

Move everything over to one side:

6n+3=-21n+3

6n=21n                                                   Subtract the 3 on the right.

-15n=0                                                                      Subtract the 21.

n=0                                                                              Divide the -15.

Subtract: write each in simplest form. 1/2-1/4=
Zepler [3.9K]

1/2-1/4

Find its LCM which would be 4

So change the 1/2 to 2/4 and keep 1/4 the same since we already have the denominator we need so

2/4-1/4 = 1/4

Simplify.<br> –6+ {14+2 (60 – 9(1+3)]}.<br> AVY V4+ UJUNDUV VA -43
Alecsey [184]

Answer:56

Step-by-step explanation:

The answer is 56.

I know this because...

-6 + {14 + 2 [60 − 9(1 + 3)]}

-6 + {14 + 2[60 − 9(4)]}

-6 + {14 + 2[60 − 36]}

-6 + {14 + 2[24]}

-6 + {14 + 48}

-6 + {62}

-6 + 62 = 56

i think.
