Simplifying
8a + 12b = 92

Solving
8a + 12b = 92

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-12b' to each side of the equation.
8a + 12b + -12b = 92 + -12b

Combine like terms: 12b + -12b = 0
8a + 0 = 92 + -12b
8a = 92 + -12b

Divide each side by '8'.
a = 11.5 + -1.5b

Simplifying
a = 11.5 + -1.5b

Point C on line segment BD. Given BD = 5x, BC = 4x, and CD = 4,
Llana [10]

Answer:

The numerical length of BD is 20 units

Step-by-step explanation:

Let us solve the question

∵ Point C lies on the line segment BD

→ That means C divides BD into 2 parts

∴ C divides BD into 2 parts BC and CD

∴ BD = BC + CD

∵ BD = 5x

∵ BC = 4x

∵ CD = 4

→ Substitute them in the equation above

∴ 5x = 4x + 4

→ Subtract 4x from both sides

∵ 5x - 4x = 4x - 4x + 4

∴ x = 4

→ Substitute the value of x in the expression of BD

∵ BD = 5x

∵ x = 4

∴ BD = 5(4) = 20

∴ The numerical length of BD is 20 units
