Answer 1

I'll help with the first one.

1.Is the following always, sometimes, or never true?

6 + 8x – 9 = 11x + 14 – 3x
always true
sometimes true
never true

6 + 8x – 9 = 11x + 14 – 3x

8x -6 = 8x + 14
-6 is not equal to 14
Never True

You start on the others.

Answer 2

1.
Solve the Equation for x:

6+8x-9=11x+14-3x


Since x is on the right-hand side of the equation
equation
A mathematical statement that says two expressions have the same value; any number sentence with an = . , switch the sides so it is on the left-hand side of the equation
equation
A mathematical statement that says two expressions have the same value; any number sentence with an = . .

11x+14-3x=6+8x-9


Subtract 9 from 6 to get -3.

11x+14-3x=-3+8x


Since 11x and -3x are like terms
term
Any expression written as a product or quotient. Example: 2xy , , or , add -3x to 11x to get 8x.

8x+14=8x-3


Since 8x contains the variable
variable
A letter used to represent a number value in an expression or an equation. to solve for, move it to the left-hand side of the equation
equation
A mathematical statement that says two expressions have the same value; any number sentence with an = . by subtracting 8x from both sides.

8x+14-8x=-3


Since 8x and -8x are like terms
term
Any expression written as a product or quotient. Example: 2xy , , or , add -8x to 8x to get 0.

0+14=-3


Remove the 0 from the polynomial
polynomial
An algebraic expression consisting of one or more summed terms, each term consisting of a constant multiplier and one or more variables raised to integral powers. ; adding or subtracting 0 does not change the value of the expression
expression
A mathematical symbol, or combination of symbols, representing a value, or relation. Example: 2+2=4 .

14=-3


Since there are no solutions
solution
1. The value of a variable that makes an equation true. 2. In chemistry, a solution is a homogeneous mixture composed of only one phase. .
