Answer:
x = -5/2
Step-by-step explanation:
4−(2x+4)=5
Distribute the minus sign
4 - 2x -4 = 5
-2x =5
Divide by -2
-2x/-2 = 5/-2
x = -5/2
Square both sides to get the binomial out of the square root:
(√(2x + 8))² = (2)²
2x + 8 = 4
2x = 4 - 8
2x = - 4
Divide both sides by 2 to isolate the variable X:
x = - 4 / 2
x = - 2
Your answer is option C.
X = sonias dvds
37 = 4x - 3
+3 +3
40 = 4x
10 = x
<span>sonia has 10 dvds</span>
14+5x=3(-x+3)-11
14+5x=-3x+9-11
14+5x=-3x-2
add 2 to both sides
16+5x=-3x
subtract 5x from both sides
16=-8x
divide both sides by -8
-2=x
Hope this helps! :)
