Question

/what is the solution for x in the equation 10x - 4.5 + 3x = 12x - 1.1

Answer 1

x = 3.4

Explanation:

Step 1: Write equation

10x - 4.5 + 3x = 12x - 1.1

Step 2: Solve for x

1. Combine like terms: 13x - 4.5 = 12x - 1.1
2. Subtract 12x on both sides: x - 4.5 = -1.1
3. Add 4.5 on both sides: x = 3.4

Step 3: Check

Plug in x to verify it's a solution.

10(3.4) - 4.5 + 3(3.4) = 12(3.4) - 1.1

34 - 4.5 + 10.2 = 40.8 - 1.1

29.5 + 10.2 = 39.7

39.7 = 39.7
