Write the English phrase as an algebraic expression. Let x represent the number. Simplify the expression, if possible. 6 less than 9 times a number

9x - 6

Step-by-step explanation:

9 times a number, x, is written as 9x

“6 less than” means to subtract 6 from something else.

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5

we would need a picture of the quadrilateral in order to answer the question. also, it seems that the question is missing some components.
