The meaning of;

In algebra, when there is an unknown number it is generally represented by a letter (such as x,y,z etc.)

The letters x in x/4 represents an unkown number.

So, x/4 represent the unknown number x divided by 4.

For example; if x=20, then;

b. x- 48 =120

step-by-step explanation:

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
