4x + 4 = 9x – 36
I need help on how to solve this
1. C, 7
2. C, 8
3. C, 7x+5=4x+5+3x
4. B,<------closed dot
5. C, k<0
6. B, q>-1
7. A, p<8
8. C, g>90
9. B, n-6≥; n≥8
There luvs
what are the answers to the whole test help my grade is so low
4x + 4 = 9x – 36
40 = 5x
8 = x
But how did you get 40 and 5x?
4x+4=9x-36
9x and 4x are positives so wouldn't it be addition ?
Same thing with -36 and +4, they are negative and positive so I was thinking I had to subtract them
THANK YOU "echoanswer"
Well, solving equations can be quite tricky sometimes, but don't worry! I'm here to help you with a touch of humor.
Let's start by gathering the x terms on one side and the constant terms on the other. We can do this by subtracting 4x from both sides:
4x - 4x + 4 = 9x - 4x - 36
Simplifying that, we get:
4 = 5x - 36
Now, let's bring the constant term, -36, to the other side by adding 36 to both sides:
4 + 36 = 5x - 36 + 36
After some basic addition:
40 = 5x
Lastly, divide both sides by 5 to solve for x:
40/5 = x
And the final answer is:
x = 8
So, the mighty "x" has been found! Hope this helps and brings a smile to your face.
To solve the given equation, we need to isolate the variable "x" on one side of the equation. Here's how to do it step by step:
1. Start by simplifying both sides of the equation. Combine like terms on each side.
4x + 4 = 9x - 36
Subtract 4x from both sides to eliminate the x term on the left side:
4 = 5x - 36
2. Next, move all the constant terms (numbers without variables) to one side of the equation. Add 36 to both sides to get rid of the -36 term on the right side:
4 + 36 = 5x
Simplify:
40 = 5x
3. Now, divide both sides of the equation by the coefficient of the variable (in this case, 5) to solve for x:
40/5 = x
Simplify:
8 = x
So, the solution to the equation is x = 8.
To confirm the solution, you can substitute the value of x back into the original equation. If both sides of the equation are equal, then the solution is correct.
