Question

(9x-4)-(3x+2) I need to know how to solve this

Answer 1

Answer:

6x - 10.

Step-by-step explanation:

Remove the parentheses.

Removing the first set does not alter the contents but with the second set of parentheses  we need to distribute the negative over the contents'

(9x - 4) - (3x + 2)

= 9x - 4 - 3x - 6

= 6x - 10.

Answer 2

Answer:

Simplifying

(9x + -4) + -1(3x + 2) = 0

Reorder the terms:

(-4 + 9x) + -1(3x + 2) = 0

Remove parenthesis around (-4 + 9x)

-4 + 9x + -1(3x + 2) = 0

Reorder the terms:

-4 + 9x + -1(2 + 3x) = 0

-4 + 9x + (2 * -1 + 3x * -1) = 0

-4 + 9x + (-2 + -3x) = 0

Reorder the terms:

-4 + -2 + 9x + -3x = 0

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

-6 + 9x + -3x = 0

Combine like terms: 9x + -3x = 6x

-6 + 6x = 0

Solving

-6 + 6x = 0

Solving for variable 'x'.

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

Add '6' to each side of the equation.

-6 + 6 + 6x = 0 + 6

Combine like terms: -6 + 6 = 0

0 + 6x = 0 + 6

6x = 0 + 6

Combine like terms: 0 + 6 = 6

6x = 6

Divide each side by '6'.

x = 1

Simplifying

x = 1

Hope this helped you! :3
