Answer 2

To solve the equations, you need to isolate the variable x. Let's solve each equation step by step:

5. -x = -7.2

Step 1: Get rid of the negative sign on the left side by multiplying both sides by -1: x = 7.2

So the solution for equation 5 is x = 7.2.

6. -x = 3/8 + 1/6

Step 1: Find a common denominator for the fractions on the right side. The common denominator is 24 (8 * 3).

• x = (3/8) * (3/3) + (1/6) * (4/4)
• x = 9/24 + 4/24

Step 2: Combine the fractions on the right side:

• x = (9 + 4) / 24
• x = 13 / 24

Step 3: Get rid of the negative sign on the left side by multiplying both sides by -1: x = -13 / 24

So the solution for equation 6 is x = -13/24.
