Question

4(x + 1) = −12 last one, please help? :)

Answer 1

4(x + 1) = -12

Distribute.

4x + 4 = -12

Subtract 4 from both sides.

4x = -16

Divide both sides by 4.

x = -4

Answer 2

I'm not sure how much you know the problem, so I'll talk about everything.

Well first thing you need to do is distribute the -4 into the (x-1)

We get
-4x+4-12

Why I got this is because when you distribute you are multiplying the -4 by the "x" and the "-1"

It becomes -4x+4 as shown above because -4 times "x" is -4x
and -4 times -1 is 4

So we have
-4x+4<12

We want to have "x" by itself on any side. The easiest side to have the "x" by itself is on the left side.
So we want to minus 4 by both sides.
The +4 will disappear and the 12 will become 8

Now its
-4x+4<12

Now its -4x<8

Now we need to divide the equation by -4.

Important! We also need to switch the sign because when you multiply or divide by a negative when dealing with this kind of equation.

Answer 3

@ANAS23 4(x + 1) = −12 is an equation NOT an inequality.

Answer 4

6 − x = 15
for this one the answer is 9 right? i tried doing it on my own but im not 100% positive its correct :/

Answer 5

nop.. not 9

Answer 6

6 − x = 15
Subtract 6.
-x = 9

^You have a -x which is the same as -1x. Divide both sides of the equation by -1.

Answer 7

x = 9 /-1

Answer 8

-9 ??

Answer 9

Yes. (:

Answer 10

seriously?
6 - x = 15
6 = 15 + x
6 - 15 = x
-9 = x

Answer 11

thank you :) i need help with one word problem but it sort of lengthy :/

Answer 12

Imagine you are teaching a fellow student how to solve:
2(x + 6) − 10 = 12 + 4(x − 1)

In your own words, explain the process for solving this equation. Please include your work at each step of the process along with the final answer.

Answer 13

i understamd if you dont wanna help with that one lol

Answer 14

I'll show you the steps. But you have to promise you'll explain it in your own words!

2(x + 6) − 10 = 12 + 4(x − 1)

The FIRST thing you always check for are the parenthesis! Use the Distributive property. ~
\[2(x + 6) − 10 = 12 + 4(x − 1)\]\[2x + 12 - 10 = 12 + 4x - 4\]
Combine like terms ~

*Remember to keep the sign in front of each term.
\[2x + 12 - 10 = 12 + 4x - 4 \]\[2x + 2 = 8 + 4x \]Subtract 2x from both sides.
\[2 = 8 + 2x \]Subtract 8 from both sides.\[-6 = 2x\]Divide both sides by 2.\[-3 = x\] So x = -3

Answer 15

@Lyndsey_Coach_xox I hope this helps! (:

Answer 16

Start by multiplying out the parentheses:

2(x + 6) − 10 = 12 + 4(x − 1)

becomes:

2x + 12 - 10 = 12 + 4x - 4

Do the arithmetic to combine like terms to get:

2x + 2 = 4x + 8

Subtract 2x from both sides:

2 = 2x + 8

Subtract 8 from both sides:

-6 = 2x

Divide both sides by 2 and flip around:

x = -3
