Question

Is u = - 1/2 a solution of 8u - 1=6u

Answer 1

No, u = 1/2

Explanation:

Step 1:

8u - 1 = 6u Equation

Step 2:

2u - 1 = 0 Subtract 6u on both sides

Step 3:

2u = 1 Add 1 on both sides

Answer:

u = 1/2 Divide

Answer 2

No

Explanation:

Step 1: Write equation

8u - 1 = 6u

Step 2: Solve for u

1. Subtract 6u on both sides: 2u - 1 = 0
2. Add 1 to both sides: 2u = 1
3. Divide both sides by 2: u = 1/2

∴ u = -1/2 is NOT a solution.
