Answer 3

To solve the equation 6.9x + 7 = 3x - 5.9, follow these steps:

Step 1: Move all the x terms to one side of the equation by subtracting 3x from both sides: 6.9x + 7 - 3x = 3x - 5.9 - 3x

Simplified: 3.9x + 7 = -5.9

Step 2: Move the constant term (7) to the other side of the equation by subtracting 7 from both sides: 3.9x + 7 - 7 = -5.9 - 7

Simplified: 3.9x = -12.9

Step 3: Isolate x by dividing both sides by 3.9: x = -12.9 / 3.9

Simplified: x ≈ -3.30769230769

So, the solution to the equation is approximately x = -3.3077.
