Answer 2

Answer:

C. 7(x + 2) - 3x = 2/3 (6x + 3)

Step-by-step explanation:

ANSWER FROM PLATO

When solving an equation, if the variable terms cancel out leaving different numbers on each side of the equal sign, then the equation has no solution.

Consider the following equation:

7(x + 2) - 3x = 2/3 (6x + 3)

   7x + 14 - 3x = 4x + 2

     4x + 14 = 4x + 2

             14 = 2

Therefore, the equation  has no solution.

Is 1 + 4(3x - 10) - 12x equivalent to -9? EXPLAIN and show your work.

Answers

Answer:

Since you have to distribute the 4 to both terms in parentheses, the equation is simplified like this:

1 + 12x - 40 -12x

= 1 - 40

= -39

Step-by-step explanation:

Answer: No

Step-by-step explanation:

1 + 4(3x - 10) - 12x = 9

simplifies to

1+12x - 40 -12x =9

combine like terms to get

-39 = 9

This is not possible so the answer is no.
