HOW DO I DO THIS 5x+(-20)=-60 2-2x=8
I can only assume this is two different questions.
On the first, add 20 to both sides. Then, divide both sides by 5
On the second, subtract two from each side, then, divide both sides by -2
To solve the equation 5x + (-20) = -60:
Step 1: Combine like terms. (-20) is already a negative, so you can remove the parentheses without changing its sign. The equation becomes 5x - 20 = -60.
Step 2: Add 20 to both sides of the equation to isolate the variable term. You do this to undo the subtraction that was done initially. The equation becomes 5x - 20 + 20 = -60 + 20. Simplifying further, you get 5x = -40.
Step 3: Divide both sides of the equation by 5 to solve for x. This step helps to isolate the variable, x. The equation becomes 5x/5 = -40/5. Simplifying further, you get x = -8.
Therefore, the solution to the equation 5x + (-20) = -60 is x = -8.
To solve the equation 2 - 2x = 8:
Step 1: Start by subtracting 2 from both sides of the equation to isolate the variable term. The equation becomes 2 - 2x - 2 = 8 - 2. Simplifying further, you get -2x = 6.
Step 2: Divide both sides of the equation by -2 to solve for x. This step helps to isolate the variable, x. The equation becomes -2x/-2 = 6/-2. Simplifying further, you get x = -3.
Therefore, the solution to the equation 2 - 2x = 8 is x = -3.
