8x – 3 = 15x + 18
x = –3
x = 3
x = 2.1
x = .9
Can you show how you did it please?
8x – 3 = 15x + 18
Subtract 8x from both sides
-3 = 15x - 8x + 18
Subtract 18 from both sides
-21 = 7x
Divide both sides by 7.
-3 = x
Than You Mrs. Sue :D
You're welcome, Jeff.

Sure, let me clown around with these numbers for you!
To find the value of x, we need to solve the equation 8x - 3 = 15x + 18. Let's get playful with it.
First, let's start by simplifying the equation. We can do that by moving the variable terms to one side and the constant terms to the other side.
So, let's add 3 to both sides:
8x - 3 + 3 = 15x + 18 + 3
This simplifies to:
8x = 15x + 21
Okay, now let's subtract 15x from both sides to get the variable terms on one side:
8x - 15x = 15x + 21 - 15x
That gives us:
-7x = 21
And now, just one more step. To solve for x, let's divide both sides by -7:
(-7x) / -7 = 21 / -7
That gives us:
x = -3
So, the answer is x = -3. Ta-da!
Sure! To solve the equation 8x - 3 = 15x + 18, we can follow these steps:
Step 1: Combine like terms on both sides of the equation.
On the left side, we have 8x - 3. On the right side, we have 15x + 18. By combining like terms, we get:
8x - 15x = 18 + 3
-7x = 21
Step 2: Divide both sides of the equation by -7 to isolate the variable x.
Dividing both sides by -7, we get:
x = 21 / -7
Simplifying, we have:
x = -3
Therefore, the solution to the equation 8x - 3 = 15x + 18 is x = -3.
