Solve for x.<br><br> x - 4.225 = 15.1

MArishka [77]

Answer:

x = 19.325

Step-by-step explanation:

You have: x - 4.225 = 15.1

Isolate x by adding 4.225 to both sides

x - 4.225 + 4.225 = 15.1 + 4.225

x = 15.1 + 4.225 = 19.325

x = 19.325

Solve the equation kx+9=7 for x

Alika [10]

Answer:

x=-2/k

Step-by-step explanation:

To solve you need to make x on one side while the other variables or numbers on the other.

First, you need to move the 9 to the other side by subtracting 9 from both sides: kx+9-9=7-9

Simplify: kx=-2

Now you need to divide by k into both sides in order to eliminate the k on kx:

x=-2/k

Answer: x=-2/k

Hope this helps!

X^4-28x^2=0 solve algebraically

Paha777 [63]

$x^4 - 28x^2 = 0$

$x^2(x^2 - 28) = 0$

$x^2 = 0 \ \ or \ \ (x^2 - 28) = 0$

$x = 0 \ \ or \ \ x^2 = 28$

$x = 0 \ \ or \ \ x = \pm \sqrt{28}$

$x = 0 \ \ or \ \ x = \pm2 \sqrt{7}$

---------------------------------------------------
Answer : x = 0 or 2√7 or -2√7
