Question

What is the answer to x in this equation K(x)=3/2x-1;k(x)=-4

Answer 1

Answer :

-1/3

Explaination :

K(x) = 3/2x - 1

K(x) = -4

K(-4) = 3 / 2(-4) - 1

K = 3 / -8 - 1

K = 3 / -9

K =

$- \frac {1}{3}$

Answer 2

Answer:

x = - 2

Step-by-step explanation:

Given k(x) = $\frac{3}{2}$ x - 1 and k(x) = - 4, then equate right sides, that is

$\frac{3}{2}$ x - 1 = - 4 ( add 1 to both sides )

$\frac{3}{2}$ x = - 3 ( multiply both sides by 2 to clear the fraction )

3x = - 6 ( divide both sides by 3 )

x = - 2
