Question

Help with Algebraic Proofs?
Given: 3(x – 4) = 33
Prove: x = 15

(STATEMENT #1:) 3(x – 4) = 33
REASON: Given

(STATEMENT #2:) 3x – 12 = 33
REASON: ?

(STATEMENT #3:) 3x – 12 + 12 = 33 + 12
REASON: ?

(STATEMENT #4:) 3x + 0 = 45
REASON: ?

(STATEMENT #5:) 3x = 45
REASON: ?

(STATEMENT #6:) x = 15
REASON: Division Property of Equality

If anyone could help me with the reasons for those statements, I would be so happy!

I'm just really bad with math in general, and I'm on a deadline, and I would really, really appreciate any help!

Answer 1

statement 1 : given
statement 2 : distributive property
statement 3 : addition property
statement 4 : combine like terms ?
statement 5 : subtraction property

I think I did that right ....you might want to get a second opinion :)
