Subtract. (9x - 8) - (x + 4)

12

Step-by-step explanation:

i used cymath if that helps

8x-12

Step-by-step explanation:

Remove these () from the first pair

9x-8-(x+4)

Subtract 9x from x - X is always one unless they give you a certain number for x to be. Also remove the remainder parenthesis from the second pair of numbers.

9x-x = 8x

Add 8 to 4

8+4 = 12

Answer is 8x-12

I hope that I explained it more to the point where you understand it

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
