789 minus x is 20
idk if u subtract or add form which side
789 - x = 20
You have to isolate for x, meaning move the 789 to the right side (making it -789):
-x = 20 - 789
-x = -769
The issue is x is negative, so we would divide by -1 to make -x, positive. What we do on one side, we do to the other.
-x/-1 = -769/-1
x = 769
Therefore, x = 769
omg thank u
ur good at answering questions btw
To solve the equation 789 - x = 20, we need to isolate the variable x on one side of the equation.
To do this, we can start by subtracting 789 from both sides of the equation. This allows us to cancel out the 789 on the left side of the equation.
Let's break it down step by step:
1. Start with the equation: 789 - x = 20
2. Subtract 789 from both sides:
(789 - x) - 789 = 20 - 789
This simplifies to:
-x = -769
3. We now have -x = -769. To solve for x, we need to isolate x on one side of the equation.
4. Multiply both sides by -1:
-1 * (-x) = -1 * (-769)
This simplifies to:
x = 769
Therefore, the value of x that satisfies the equation 789 - x = 20 is x = 769.
