Answer:

So lets isolate y

we have

-2x+3y=9

2/3x +2y=0

Im gonna do the first equation

so -2x + 3y = 9

Add 2x on both sides

3y= 9+ 2x

Now divide by 3 to isolate y

y= 3+ 2/3x

Now we can subsitute y into any eqaution (I’m gonna do the second one) to solve.

2/3x+ 2(3+ 2/3x)= 0

Solve:

2/3x+ 6 + 4/3x = 0

6/3x +6= 0

2x+6=0

2x= -4

x= -2

Now we can subsitute this for any equation.

so I’m gonna do the first equation

-2(-2)+3y=9

4+3y=9

3y= 5

y= 5/3

y= 1 2/3

Final answer:

x=-2

y= 1 2/3

PLLSSS REALLY URGENT <br> If g(x)=3x+4, determine n that g(-3)=g^-1(n).
grigory [225]

Answer:

we have:

g(-3) = 3.(-3) + 4 = -5

g {}^{ - 1} (n) =  \frac{1}{3n + 4}

because

g( - 3) = g {}^{ - 1} (n)

=>

- 5 =  \frac{1}{3n + 4} \\  \\  <  =  >  - 5(3n + 4) = 1 \\  \\  <  =  >  - 15n - 20 = 1 \\  \\  <  =  > n =  \frac{ - 21}{15}  \\  \\  <  =  > n =  \frac{ - 7}{5}
