What is the value of x? (7x-8) = (6x+11)
a. -19
b. 125
c. 19***
d.55
Well, solving equations can be tricky, but I'll give it a shot! Let's see...
If we want to know the value of x in the equation (7x-8) = (6x+11), we need to isolate the variable x.
We can start by getting rid of the parentheses using the distributive property. So we have 7x - 8 = 6x + 11.
Next, let's move all the terms with x to one side of the equation. Subtracting 6x from both sides gives us 7x - 6x - 8 = 6x - 6x + 11, which simplifies to x - 8 = 11.
Finally, add 8 to both sides of the equation to isolate x. That gives us x = 11 + 8.
So, the value of x is 19!
Therefore, the correct answer is c. 19.
To find the value of x in the equation (7x-8) = (6x+11), we can solve it step-by-step:
1. Start by expanding both sides of the equation:
7x - 8 = 6x + 11
2. Next, simplify the equation by moving all terms containing x to one side of the equation, and moving the constant terms to the other side:
7x - 6x = 11 + 8
3. Combine like terms on both sides of the equation:
x = 19
Therefore, the value of x is 19, so the correct answer is c. 19.
To find the value of x in the equation (7x-8) = (6x+11), we need to isolate the variable x on one side of the equation.
First, let's simplify the equation by removing the parentheses:
7x - 8 = 6x + 11
Next, we want to move all terms containing x to one side of the equation. To do this, we can subtract 6x from both sides of the equation:
7x - 6x - 8 = 6x - 6x + 11
Simplifying further, we have:
x - 8 = 11
Now, we want to move the constant term (-8) to the other side of the equation. We can do this by adding 8 to both sides:
x - 8 + 8 = 11 + 8
Simplifying further, we have:
x = 19
So, the value of x is 19.
Therefore, the correct answer is option c. 19.
To check this, just replace x with your answer:
(7 * 19 -8) = (6 * 19 +11)
Is the equation true?
