Answer 3

To solve the equation (12 + x) / (-3) = (-7) / 3.5, you'll need to follow these steps:

Step 1: Simplify the expressions on both sides of the equation.

(12 + x) / (-3) simplifies to -4 - (x/3) because dividing by a negative number flips the sign, and -3 goes into 12 four times.

(-7) / 3.5 simplifies to -2 because -7 divided by 3.5 equals -2.

Now, the equation becomes:

-4 - (x/3) = -2

Step 2: Isolate the variable x on one side of the equation. To do this, we need to get rid of the constant term on the left side (-4). We can do this by adding 4 to both sides of the equation.

-4 - (x/3) + 4 = -2 + 4

Simplifying further:

• (x/3) = 2

Step 3: To solve for x, multiply both sides of the equation by 3 to get rid of the fraction.

3 * (-x/3) = 3 * 2

Simplifying further:

• x = 6

So the solution to the equation is x = 6.
