Answer: x = 2/3
Step-by-step explanation:
<em>Add all sides.</em>
2x-2 + 2x - 2 + x + x =
6x - 4
<em>Put " = 0 "</em>
6x-4 = 0
Add 4 to both sides.
6x-4 = 0
+4 = +4
-------------------
6x=4
You get 6x = 4 because the 4 on the left side of the equals sign cancelled out!
<em></em>
<em>NOW DIVIDE 6 FROM BOTH SIDES</em>
6x = 4
/6 /6
-----------
x= 4/6
<em>SIMPLIFY / REDUCE FRACTION</em>
4/6 divided by 2 = 2/3
2/3 is the answer !

Answer:
y² - 4
Step-by-step explanation:
Give the expression :
"the square of y decreased by the quotient of 28 and 7"?
Expressing Mathematically ;
Square of y = y²
Quotient of 28 and 7 is obtained by taking the division of 28 by 7
Dividing 28 by 7 ; 28/7 = 4
Hence, decreasing y² by 4 ; we have ;
y² - 4
