if -1/7x - 6 = 34, find the value of -2x + 3
a) -280
b) -77
c) 395
d) 563
Can you pls explain it for me too
First solve the given equation for x.
-1/7 x = 40
x = -280 is the answer. Do you see why?
Next step:
Compute -2x + 3.
That would be -2(-280) + 3.
Which of the choices is that?
oh, its d!
thanks so much
To find the value of `-2x + 3`, we first need to solve the equation `-1/7x - 6 = 34` to find the value of `x`. Then we substitute the value of `x` in `-2x + 3` to get the final answer.
Let's solve the equation `-1/7x - 6 = 34` step by step:
Step 1: Add 6 to both sides of the equation to isolate `-1/7x` on one side:
`-1/7x - 6 + 6 = 34 + 6`
`-1/7x = 40`
Step 2: Multiply both sides by -7 to eliminate the fraction `-1/7`:
`(-1/7x) * (-7) = 40 * (-7)`
`x = -280`
Now that we have the value of `x = -280`, let's substitute it into `-2x + 3` to find the final answer:
`-2(-280) + 3 = 560 + 3 = 563`
So the value of `-2x + 3` is `563`, which corresponds to option d).
