Answer: This equation has <u>one solution.</u>
Steps:
2+4(3-4x) = 5x +9
First, we need to distribute to the terms inside the parentheses.
4 * 3 = 12 and 4 * -4= -16x
Our equation now looks like this:
2 + 12 - 16x = 5x + 9
We can now combine like terms. We have 2 like terms that we can combine:
2 + 12 + = 14
Our equation now looks like this:
-16x + 14 = 5x + 9
We can now use inverse operations to get rid of 5x. The inverse operation for addition is subtraction; so we subtract 5x on both sides. Remember, our goal is to isolate the x.
-16x + 14 = 5x + 9
-5x -5x
The fives cancel out. Our equation now looks like this:
-21x + 14 = 9
We can now use inverse operations to get rid of the 14:
-21x + 14 = 9
- 14 -14
The fourteens cancel out. Our equation now looks like this:
-21x = -5
Last step! Now we use inverse operations to isolate the x. -21 is being multiplied by x; the inverse operation for multiplication is division.
-21x/-21 = and -5/-21 = 5/21
x is equal to 5/21.
Hope this helps!

Step-by-step explanation:
No.
The distance between 19 and 15 is 4. Both numbers are positive, 4 units apart.
The distance between -19 and -15 is also 4. Both numbers are negative, 4 units apart.
When you find the distance from 19 to -15, keep in mind that one number is positive, 19, and one number is negative, -15. The two numbers are on different side of zero on the number line.
Start at -15. -15 is 15 units to the left of zero. To get to 0, you need to go 15 units right. Now you need to go from 0 to 19. That is another 19 units right. Add 15 + 19 to get 34.
The distance from 19 to -15 on a number line is not 4. It is 34.

All you have to do is subtract -12.6 C from 7.5 C which equals -20.1
-12.6 - 7.5 = -20.1
