Equality Properties

Explanation:

Step 1: Define Equation

7x + 2 = 4x + 11

Step 2: Solve for x

1. Subtract 4x on both sides: 3x + 2 = 11
2. Subtract 2 on both sides: 3x = 9
3. Divide 3 on both sides: x = 3

Step 3: Check

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

1. Substitute in x: 7(3) + 2 = 4(3) + 11
2. Multiply: 21 + 2 = 12 + 11
3. Add: 23 = 23

Here we see that 23 does indeed equal 23.

∴ x = 3 is the solution to the equation.
