Question

Maths question. Solve 4(x - 1) = 2(6 - 2x)

Answer 1

Use distributive property
4x - 4 = 12 - 4x
8x = 16
X = 2

Step-by-step explanation:

Step 1: Define equation

4(x - 1) = 2(6 - 2x)

Step 2: Solve for x

1. Distribute:                              4x - 4 = 12 - 4x
2. Add 4x on both sides:          8x - 4 = 12
3. Add 4 to both sides:             8x = 16
4. Divide 8 on both sides:        x = 2

Step 3: Check

Plug in x into the original equation to verify it's a solution.

1. Substitute in x:                    4(2 - 1) = 2(6 - 2(2))
2. Multiply:                               4(2 - 1) = 2(6 - 4)
3. Subtract:                              4(1) = 2(2)
4. Multiply:                               4 = 4

Here we see that 4 does indeed equal 4.

∴ x = 2 is a solution of the equation.
