The value of g^-1(-3) is the value of x that makes g(x) = -3. To find it, we can solve
.. (x +4)/(2x -5) = -3
.. x +4 = -3(2x -5)
.. 7x = 11
.. x = 11/7

The desired value is
.. (3/11)*g^-1(-3)
.. = (3/11)*(11/7)
.. = 3/7

$\frac{3}{11} g^{-1}(-3) = \frac{3}{7}$

All you have to do is move the denominator on the other side, by multiplying.

a-10
------- = -9
20

multiply 20 x -9
= -180

then it becomes a-10=-180
+10 +10
a=-170

Which ordered pair is the solution to the system of linear equations y = -7x + 2 and y = 9x - 14?

lisabon 2012 [21]

Y = -7x + 2
y = 9x - 14

-7x + 2 = 9x - 14
14 + 2 = 9x + 7x
16 = 16x
1 = x

y = -7x + 2
y = -7(1) + 2
y = -7 + 2
y = -5

solution is : (1,-5) <==
