Answer 2

To solve the equation 5x - 0.7 = -2.4, you need to isolate the variable x on one side of the equation. Follow these steps to solve for x:

Step 1: Add 0.7 to both sides of the equation to get rid of the constant term on the left side: 5x - 0.7 + 0.7 = -2.4 + 0.7

Simplified equation: 5x = -1.7

Step 2: Now, to find the value of x, divide both sides of the equation by 5: 5x / 5 = -1.7 / 5

Simplified equation: x = -0.34

So the value of x is -0.34.
