Proof #1(Copy the T-charton your paper!!)
STEP1. 3x = 7 – 1/2x
2. 6x = 14 – x
3. 7x = 14
4. x = 2
REASON1. GIVEN
2. Multiplication Property
3. Addition Property
4. Division Property
It will give you the 1st stepFirst reason is always “given”

TOO: 3 Steps
Step1. 2x + 3 = 11
2. 2x = 8
3. x = 4
Reason1. Given
2. Subtraction Property
3. Division Property
