12 = \frac{1+a}{1-a} => 12(1-a)= 1+ a \\=> 12 -12a = 1 + a => 12a+1 = 12-1 \\=> 13a = 11 => a= \frac{11}{13}

ok done. Thank to me :>

10 divided by 2-(16 divided by 4) +14
ankoles [38]

Answer:

15

Step-by-step explanation:

okay so you gotta use pemdas (p = parentheses, e = exponents, m = multiplication, d = division, a = addition, s = subtraction), but for the multiplication/division and addition/subtraction parts, if  division or subtraction happens first then you must do it first rather than doing multiplication or addition first

10 / 2 -(16/4) + 14

10 / 2 -(4) + 14

5 - 4 + 14

1 + 14

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.
