What is -(x + 4) - 3x = x in Distributive property?
1 answer:
Answer:
x = -4/5
Step-by-step explanation:
Original equation: -(x+4)-3x=x
Remember distributive property allows us to get rid of the parenthesis by bringing a multiplication from outside to inside a parenthesis.
-(x+4) = -x-4
= -x-4-3x=x
Now we combine like terms in this case we have (-x) and (-3x)
= -4x-4=x
Subtract x from both sides
= -4x-4=x
-x -x
----------------
-5x-4=0
Add 4 to both sides
-5x-4=0
+4 +4
---------------
-5x=4
Our final step is to divide both sides by -5
-5x=4
---- ----
-5 -5
x = -4/5

Answer: x=68/11 and y=-72/11
Steps:
2(x+4y=-20)
2x+8y=-40
2x - 3y = 32
- 2x + 8y = -40
-11y=72
y=-72/11
x + 4(-72/11) = -20
x - 288/11 = -20
x=68/11
Answer:
15
Step-by-step explanation:
First add 20 to both sides to get x/3 = 5
Then multiply both sides by 3 to get 15.
You can check it by substituting it into the equation
15/3 - 20 = -15
5 - 20 = -15
-15 = -15
