Answer: The equation that has the solution x = 5 is 32−4x=12

Step-by-step explanation:

Hi, to answer this question we have to solve each equation and the one that has the solution x=5 is the correct.

The equation that has the solution x = 5 is 32−4x=12.

To confirm the answer we have to solve the equation by isolating the variable x.

32−4x=12

-4x = 12 -32

-4x = -20

x = -20 / -4

x =5

Feel free to ask for more if it´s necessary or if you did not understand something.

It would be 32-4x=12
32-4(5)=12
32-20=12
12=12

Q(x)= 1/2x - 3; q(x) =-4. Find the value of x

Lelu [443]

Answer:

$q(x) =-5$

Step-by-step explanation:

I am solving this using Function Notation.

We are given:

$q(x)= \frac{1}{2}x - 3$

While we are to find:

$q(x) =-4$

In Function Notation, replace all the " $x$ " you see with the value you are given.

So, in this case,

$q(x)= \frac{1}{2}x - 3\\\\=\frac{1}{2}x - 3$

Would become

$q(x)= \frac{1}{2}x - 3\\\\=\frac{1}{2}(-4) - 3$

Now we can solve.

$\frac{1}{2}(-4) - 3$

Use PEMDAS; Parenthesis first;

$\frac{1}{2}(-\frac{4}{1})$

Cross divide: 1 cancels 1, -4 ÷ 2 = -2

Hence, we are left with

$(-2) - 3$

$-5$

Therefore, the value of x is -5
