Question

b) (6x - 30)÷(2x - 10)​

Answer 1

Step-by-step explanation:

Simplifying

6x + -10 = 2x + -30

Reorder the terms:

-10 + 6x = 2x + -30

Reorder the terms:

-10 + 6x = -30 + 2x

Solving

-10 + 6x = -30 + 2x

Solving for variable 'x'.

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

Add '-2x' to each side of the equation.

-10 + 6x + -2x = -30 + 2x + -2x

Combine like terms: 6x + -2x = 4x

-10 + 4x = -30 + 2x + -2x

Combine like terms: 2x + -2x = 0

-10 + 4x = -30 + 0

-10 + 4x = -30

Add '10' to each side of the equation.

-10 + 10 + 4x = -30 + 10

Combine like terms: -10 + 10 = 0

0 + 4x = -30 + 10

4x = -30 + 10

Combine like terms: -30 + 10 = -20

4x = -20

Divide each side by '4'.

x = -5

Simplifying

x = -5
