Answer:

The correct option is C) -16

Step-by-step explanation:

Consider the provided equation.

$7x-2(x + 1) = 6x + 14$

Open the parentheses

$7x-2x -2 = 6x + 14$

Add the like terms.

$5x -2 = 6x + 14$

Subtract 5x from both the sides.

$-2 = x + 14$

Subtract 14 to the both sides.

$x=-16$

Hence, the correct option is C) -16

Simplify the following expression 6X2 plus 8X -3 minus 3X2-6

Murrr4er [49]

Answer:

-24

Step-by-step explanation:

I´m guessing by the big x sign you want me to multiply so the first step in the equation is to multiply because of PEMDAS so(6*2)+(8*-3)-3*2-6,

so 6*2=12,8*-3=-24,-3*2=-6

12+-24-6-6,

12-24=-12,-6+-6=-12

-12+-12=-24

3/4(8x-4)=7x+2, I need to find out the answer

laiz [17]

Answer: x = -5

Step-by-step explanation:

First convert 3/4 to decimal= 0.75

0.75 (8x - 4) = 7x + 2

6x - 3 = 7x + 2

Transpose 7x from right hand side to the left hand side

6x - 7x = 2 + 3

-x = 5

x = -5

I hope this helps.
