If x/−5 =2 , then what is the value of x
?(1 point)
$$
The value of x can be found by multiplying both sides of the equation by -5 to isolate x.
x/(-5) = 2
x = 2*(-5)
x = -10
Therefore, the value of x is -10.

−34x=52 and 52x=−34
To determine which pair of equations has exactly the same solution, we need to find the solution for each pair. Let's solve each pair:
1. -3.2x = 0.64 and x/4 = -0.05
From the first equation: x = 0.64 / -3.2 = -0.2
From the second equation: x = -0.05 * 4 = -0.2
Both equations have the same solution x = -0.2
2. 3/8 x = 1 and 1/3 x = 1/8
From the first equation: x = 1 / (3/8) = 8/3
From the second equation: x = (1/8) / (1/3) = 3/8
The solutions are different, not exactly the same.
3. x/3.2 = 1.8 and 1.8x = 3.2
From the first equation: x = 1.8 * 3.2 = 5.76
From the second equation: x = 3.2 / 1.8 = 1.77778
The solutions are different, not exactly the same.
4. -3/4 x = 52 and 52x = -34
From the first equation: x = 52 / (-3/4) = -69.3333
From the second equation: x = -34 / 52 = -0.6538
The solutions are different, not exactly the same.
So, the pair of equations that have exactly the same solution is -3.2x = 0.64 and x/4 = -0.05.
u sure
I apologize for the confusion in my previous response. Let's reassess the pair of equations:
-3.2x = 0.64 and x/4 = -0.05
We can simplify the second equation to find the value of x:
x = -0.05 * 4
x = -0.2
Now, we substitute x = -0.2 into the first equation:
-3.2 * (-0.2) = 0.64
0.64 = 0.64
As both equations simplify to the same value, the pair -3.2x = 0.64 and x/4 = -0.05 has exactly the same solution of x = -0.2.
Thank you for pointing out the need for verification, and I appreciate your patience.
