2x4=8Step-by-step explanation:
1. Since 2x2x does not contain the variable to solve for, move it to the right side of the equation by subtracting 2x2x from both sides.−3y=−2x+8-3y=-2x+8Divide each term by −3-3 and simplify.
Divide each term in −3y=−2x+8-3y=-2x+8 by −3-3.<span><span>−3y−3=−2x−3+8−3</span><span>-3y-3=-2x-3+8-3</span></span>Simplify the left side of the equation by canceling the common factors.

Answer: The number is: "2" .
_______________________________________________________
The expression is: 2 − (½)x = (½)<span>x ;
</span>→<span> in which "x" is the "unknown number".
</span>_______________________________________________________
Explanation:
______________________________________________________
Given:
_________________________________________________________
"Two decreased by a half of a number is one-half<span> of the number" ;
Let "x" represent the "unknown number" for which we wish to solve;
Write the expression as:
_________________________________________________
" </span>2 − (½)x = (½)x " .
_________________________________________________
Note: Add "(½)x" to EACH SIDE of the equation:
_________________________________________________
2 − (½)x + (½)x = (½)x + (<span>½)</span>x ;
to get:
_________________________________________________
→ 2 = 1x ;
↔ 1x = 2 ;
↔ x = 2 .
