Hey all! This is the another one, pls show the working......
zhannawk [14.2K]

Answer:

Hi again, I'm here to answer!

The correct answers:

10. x = -7 2/3

11. x = 2

12. x = 3

Step-by-step explanation:

(x + 3)/2 = (x - 4)/5

(5x + 15)/10 = (2x - 8)/10

3x/10 = -23/10

x = -23/3

x = -7 2/3

(2x - 1)/3 = x/2

(4x - 2)/6 = 3x/6

x/6 = 2/6

x = 2

(3x + 1)/5 = 2x/3

(9x + 3)/15 = 10x/15

-x/15 = -3/15

x = 3

Hope this helped!

Make an equation and then solve it, show all your work.
Daniel [21]
The equation appears to be made already.

Using the Order of Operations, consider what operations are being done to the variable "c". They are
• divide c by 4
• add -5 to the quotient.

To find the value of "c", we "undo" these operations in reverse order. To undo the addition of a number, we add the opposite of the number. So, we will first
• add 5 to the equation
This gives
\dfrac{c}{4}-5+5=4+5\\\\\dfrac{c}{4}+0=9\\\\\dfrac{c}{4}=9

Now, the next operation that we need to undo is the division by 4. We can undo that by multiplying the equation by 4. So, we will next
• multiply the equation by 4
This gives
4\cdot \dfrac{c}{4}=4\cdot 9\\\\c\cdot \dfrac{4}{4}=36\\\\c \cdot 1=36\\\\c=36

The solution is c = 36.
