Question

Solve: 1.3(w+4)=2.1w+3.6

Answer 1

w = 2

Explanation:

Step 1: Write equation

1.3(w + 4) = 2.1w + 3.6

Step 2: Solve for w

1. Distribute 1.3: 1.3w + 5.2 = 2.1w + 3.6
2. Subtract 1.3w on both sides: 5.2 = 0.8w + 3.6
3. Subtract 3.6 on both sides: 1.6 = 0.8w
4. Divide both sides by 0.8: 2 = w
5. Rewrite: w = 2

Step 3: Check

Plug in w to verify it's a solution.

1.3(2 + 4) = 2.1(2) + 3.6

1.3(6) = 4.2 + 3.6

7.8 = 7.8
