Step-by-step explanation:

Simplify the left side:

5x - 20 = 3x + 4

Move all terms containing x to the left side of the equation:

2x - 20 = 4

Move all terms not containing x to the right side of the equation:

2x = 24

Divide each term by 2 and simplify:

x = 12

Answer:

$\boxed{\bold{x=12}}$

Step-by-step explanation:

Add 20 to both sides

$\bold{5x-20+20=3x+4+20}$

Simplify

$\bold{5x=3x+24}$

Subtract 3x from both sides

$\bold{5x-3x=3x+24-3x}$

Simplify

$\bold{2x=24}$

Divide both sides by 2

$\bold{\frac{2x}{2}=\frac{24}{2}}$

Simplify

$\bold{x=12}$

Write the equation of the circle centered at ( 4 , − 5 ) with radius 18.

Free_Kalibri [48]

Answer:

(x-4)^2 + (y+5)^2 = 324

Step-by-step explanation:

The equation of a circle is given by the equation (x-h)^2 + (y-k)^2 = r^2, where (h,k) is the center point of the circle.

Therefore, since the center point of the circle and the radius is given, we can just plug the numbers into the formula:

(x-4)^2 + (y+5)^2 = 18^2
