Answer:
x = 2
General Formulas and Concepts:
Pre-Algebra
- Order of Operations: BPEMDAS
- Equality Properties
Explanation:
Step 1: Define equation
4(x - 1) = 2(6 - 2x)
Step 2: Solve for x
- Distribute: 4x - 4 = 12 - 4x
- Add 4x on both sides: 8x - 4 = 12
- Add 4 to both sides: 8x = 16
- Divide 8 on both sides: x = 2
Step 3: Check
Plug in x into the original equation to verify it's a solution.
- Substitute in x: 4(2 - 1) = 2(6 - 2(2))
- Multiply: 4(2 - 1) = 2(6 - 4)
- Subtract: 4(1) = 2(2)
- Multiply: 4 = 4
Here we see that 4 does indeed equal 4.
∴ x = 2 is a solution of the equation.
