Answer:
- The value of x that satisfies the equation -8x + 7 - x = 70 is x = -7.
Explanation:
To solve the equation -8x + 7 - x = 70, we can combine like terms and isolate the variable x.
First, let's combine the terms that have x:
-8x - x = -9x
Next, let's combine the constant terms:
7 = 70
Now, let's rewrite the equation with the combined terms:
-9x + 7 = 70
To isolate the variable x, we need to get rid of the constant term 7. We can do this by subtracting 7 from both sides of the equation:
-9x + 7 - 7 = 70 - 7
Simplifying the equation:
-9x = 63
Now, we can solve for x by dividing both sides of the equation by -9:
(-9x) / -9 = 63 / -9
Simplifying the equation further:
x = -7
So, the solution to the equation -8x + 7 - x = 70 is x = -7.
To summarize:
- The value of x that satisfies the equation -8x + 7 - x = 70 is x = -7.
