Equality Properties

Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtraction Property of Equality

Step-by-step explanation:

Step 1: Define

-8 = 16x + 9

Step 2: Solve for x

[Subtraction Property of Equality] Subtract 9 on both sides: -17 = 16x[Division Property of Equality] Divide 16 on both sides: -17/16 = xRearrange/Rewrite: x = -17/16

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x: -8 = 16(-17/16) + 9Multiply: -8 = -17 + 9Add: -8 = -8

Here we see that -8 does indeed equal -8.

∴ x = -17/16 is the solution to the equation.
