Question

Q(x) = 1⁄2x−3; q(x) = −4

Answer 1

X= -1/2 is the answer

Answer 2

Solving with Functions

We can solve with functions exactly as we do algebraic equations. Our goal is to isolate the variable.

Solving the Question

We're given:

`q(x) = (1)/(2)x-3\\\\q(x) = -4`

Solve using substitution:

`(1)/(2)x-3=-4`

Isolate x:

`(1)/(2)x=-4+3\\\\(1)/(2)x=-1\\\\x=-2`

Answer

x = -2
