Answer 3

To solve the equation -7x = 17.5, follow these steps:

Step 1: Isolate the variable term (x) on one side of the equation. To do this, we'll get rid of the constant term (-7x) on the left side by adding 7x to both sides of the equation:

-7x + 7x = 17.5 + 7x

Step 2: Simplify the equation:

0 = 17.5 + 7x

Step 3: Now, isolate the variable (x) term on one side. To do this, subtract 17.5 from both sides of the equation:

0 - 17.5 = 17.5 + 7x - 17.5

Step 4: Simplify the equation:

-17.5 = 7x

Step 5: Finally, solve for x by dividing both sides of the equation by 7:

x = -17.5 / 7

Step 6: Calculate the result:

x ≈ -2.5

The solution to the equation is x ≈ -2.5.
