Answer:

( 6 4 − 1 3 − 8 ) − 1 ( 5 4 + 6 − 8 3 )

Step-by-step explanation:

Rearrange terms

( 6 4 − 1 3 − 8 ) − 1 ( 5 4 + 6 − 8 3 )    ( 6 4 − 1 3 − 8 ) − 1 ( 5 4 − 8 3 + 6 )

distribute

(6 4 − 1 3 − 8 ) − 1 ( 53   4 − 8 3 + 6 )     (6 4 − 1 3 − 8 ) − 5 4+ 8 3 − 6  

Eliminate redundant parentheses        

combine like terms

multiply like 1

solution: 4 + 7 3 − 1 4

Multiply −3-3 by −1-1.

6y4−y−8y+3y46y4-y-8y+3y4

Simplify by adding terms.

Add 6y46y4 and 3y43y4.

9y4−y−8y9y4-y-8y

Subtract 8y8y from −y-y.

How many solutions does the equation 6(x -2) = 8 + 6x have?
Contact [7]

Answer:

There are no solutions.

Step-by-step explanation:

First simplify the equation.

<u>6(x - 2)</u> = 8 + 6x

Distribute.

6x - 12 = 8 + 6x

Adding 8 to a number and subtracting 12 from the same number to get the same answer doesn't make sense so there are no solutions.
