Answer 2

To solve the equation 1.2x - 5.6 - 0.5x + 8.5 = 0, follow these steps:

Step 1: Combine like terms on the left side of the equation: (1.2x - 0.5x) - 5.6 + 8.5 = 0 0.7x - 5.6 + 8.5 = 0

Step 2: Simplify further: 0.7x + 2.9 = 0

Step 3: Isolate the variable x on one side of the equation: 0.7x = -2.9

Step 4: Solve for x by dividing both sides by 0.7: x = -2.9 / 0.7

Step 5: Calculate the value of x: x ≈ -4.14

So, the solution to the equation is approximately x = -4.14.
