Question

Solve for x: 2/5(x-2)=4x

Answer 1

x = -2/9

Explanation:

Multiply both sides by 5

2(x - 2) = 4x*5

2x - 4 = 20x Subtract 2x from both sides

-4 = 18x Divide by 18

-4/18 = x

x = -2/9

Explanation:

Step 1: Define

2/5(x - 2) = 4x

Step 2: Solve for x

1. Distribute 2/5: 2/5x - 4/5 = 4x
2. Subtract 2/5x on both sides: -4/5 = 18/5x
3. Divide both sides by 18/5: -2/9 = x
4. Rewrite: x = -2/9
