Answer:
x is equal to one and two fifths.
Step-by-step explanation:
Given:
12x - 15 = 6 - 3x
Let's start by noticing that every term in that equation is divisible by 3. That means we can factor 3 out of it, giving us:
4x - 5 = 2 - x
Now we'll add x to both sides:
4x + x - 5 = 2 - x + x
5x - 5 = 2
An then we add 5 to both sides:
5x - 5 + 5 = 2 + 5
5x = 7
Finally, we can divide both sides by 5 to get the final answer:
5x ÷ 5 = 7 ÷ 5
x = 7/5
To put that in proper form it would be:

<h3>How to find area of a rectangle?</h3>
A rectangle is a quadrilateral. It has 2 opposite sides equal to each other.
Therefore,
area of rectangle = lw
where
- l = length
- w = width
Therefore,
length = 1 2 / 3 = 5 / 3 ft
width = 5 / 8 ft
area = 5 / 3 × 5 / 8
area = 25 / 24 ft
area = ft
