Answer:

x= 6

Explanation:

3-2x= -1.5x

-3 -3

-2x= -1.5x - 3

+1.5x +1.5x

-.5x= -3

divide both sides by -.5

x = 6

Equality Properties

Explanation:

Step 1: Define Equation

3 - 2x = -1.5x

Step 2: Solve for x

  1. Add 2x on both sides: 3 = 0.5x
  2. Divide 0.5 on both sides: 6 = x
  3. Rewrite: x = 6

Step 3: Check

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

  1. Substitute in x: 3 - 2(6) = -1.5(6)
  2. Multiply: 3 - 12 = -9
  3. Subtract: -9 = -9

Here we see that -9 does indeed equal -9.

∴ x = 6 is the solution to the equation.
