Answer:
y = (-1/2)x - 1
Step-by-step explanation:
y - 1 = (-1/2)(x - (-4))
y - 1 = (-1/2)(x + 4)
y - 1 = (-1/2)x -(1/2)(4)
y - 1 = (-1/2)x - 2
y = (-1/2)x -2 + 1
2/5 ≥ x - (4/5). add 4/5 to each side
6/5 ≥ x
Answer: The number is: "2 " .
__________________________________________
Explanation:
__________________________________________
Write the expression; which is an equation, as follows:
__________________________________________
" 4x <span>− 12 = 2(-x) " ; in which "x" represents "the number for which we shall solve" .
___________________________________________
Note:
If the "number" = "x" ; the "opposite of the number" = " -x " ;
</span>___________________________________________
Rewrite as: " 4x <span>− 12 = -2x " ;
</span>_____________________________________________
→ Add "12" ; & add "2x" ; to EACH SIDE of the equation:
4x − 12 + 12 + 2x = -2x + 12 + 2x ;
to get: 6x = 12 ;
____________________________________________________
Now, divide each side of the equation by "6" ;
to isolate "x" on one side of the equation; & to solve for "x" ;
____________________________________________________
6x / 6 = 12 / 6 ;
to get: x = 2 .
____________________________________________________
Answer: The number is: "2 " .
____________________________________________________
Let us check our answer, by plugging in "2" for "x" in our original equation:
_____________________________________________________
→ " 4x − 12 = 2(-x) " ;
Let us plug in "2" for "x" ; to see if the equation holds true; that is; if both side of the equation are equal; when "x = 2" ;
→ " 4(2) − 12 = ? 2(-2) ??
→ 8 − 12 = ? -4 ? ;
→ -4 = ? -4 ?? Yes!

Answer:
x=5
Step-by-step explanation:
10 +3x = 5x
Subtract 3x from each side
10+3x-3x= 5x-3x
10 =2x
Divide each side by 2
10/2 = 2x/2
5 =x
