2 plus StartFraction x over negative 10 EndFraction equals StartFraction 2 over 5 EndFraction
To solve the equation, we need to isolate the variable x.
We are given the equation: 2 + (x / -10) = 2/5
To start, we can simplify the equation by multiplying both sides by -10 to eliminate the fraction:
-10*(2 + (x / -10)) = -10*(2/5)
-20 + x = -4
Next, we can isolate the variable x by moving the constant term -20 to the other side of the equation:
x = -4 + 20
x = 16
Therefore, the solution to the equation is x = 16.
To solve the equation, we'll start by isolating the variable, x.
The given equation is:
2 + (x/-10) = (2/5)
To remove the fraction, we'll multiply through the equation by -10:
(-10) * (2 + (x/-10)) = (-10) * (2/5)
Simplifying, we get:
-20 - x = -20/5
Next, we simplify the fraction on the right side by dividing 20 by 5:
-20 - x = -4
To isolate x, we can move -20 to the other side by adding it to both sides of the equation:
-20 - x + 20 = -4 + 20
Simplifying further:
-x = 16
Since we want to solve for x, we need to isolate it by multiplying both sides of the equation by -1 to change the sign of x:
(-1) * (-x) = (-1) * 16
x = -16
Therefore, the solution to the equation is x = -16.
