Solve for X:
21⋅(8−x)+21x=12−x
To solve the equation 21⋅(8−x)+21x=12−x, follow these steps:
- Step 1: Use the distributive property on the left side of the equation.
- Distribute 21 across (8−x):
- This gives us 21⋅8−21⋅x+21x.
- Simplify the terms: 4−21x+21x.
- Step 2: Simplify the left side of the equation:
- The terms −21x and 21x cancel each other out.
- Thus, the left side simplifies to 4.
- Step 3: Set the simplified equation equal to the right side:
- So, we have 4=12−x.
- Step 4: Solve for x using basic algebra:
- Add x to both sides to move x to one side: x+4=12.
- Subtract 4 from both sides to solve for x: x=12−4.
- This results in x=8.
Therefore, the solution to the equation is x=8.
