The model represents an equation. What value of x makes the equation true? Please write an explanation on why. I don’t just want the answer I actually want to learn and understand it, thank you! :>

A) 29/8

Step-by-step explanation:

On the left side of the equals sign, we have five x's and nine -1's.

On the right side of the equals sign, we have three -x's and twenty 1's.

Both sides are equal, so:

5(x) + 9(-1) = 3(-x) + 20(1)

5x − 9 = -3x + 20

Add 3x to both sides.

8x − 9 = 20

Add 9 to both sides.

8x = 29

Divide both sides by 8.

x = 29/8

For question 1: a. 48.0

b. 163.0

c.19.0

For question 2: a. 10.60

b.8.90

c.14.90

Explanation: all you have to do is if they ask you for round the numbers to 1 decimal place, you have to round the number next to decimal. For example: 0.75=0.8 and the same thing is for the 2 decimal place. For example: 2.076=2.08\

Hope this will help you
