Question

1.5(2x-4)+0.5(6x+10)-x=5

Answer 1

3х-6+3х+5-х=5
5х-1=5
5х=6
х=1.2

Answer 2

To solve the equation 1.5(2x-4) + 0.5(6x+10) - x = 5, we can follow these steps:

Step 1: Distribute the coefficients: 1.5 * 2x = 3x 1.5 * -4 = -6 0.5 * 6x = 3x 0.5 * 10 = 5 -x = -x

So the equation becomes: 3x - 6 + 3x + 5 - x = 5

Step 2: Combine like terms: 3x + 3x - x = 3x -6 + 5 = -1

So the equation simplifies to: 3x + 3x - x = 5 - 1

Step 3: Further simplify: 3x + 3x - x = 4x 5 - 1 = 4

The equation now becomes: 4x = 4

Step 4: Solve for x: Divide both sides of the equation by 4: 4x/4 = 4/4 x = 1

Therefore, the solution to the equation 1.5(2x-4) + 0.5(6x+10) - x = 5 is x = 1.
