Question

Write a two-column proof

it says Given: the top number is 2x+6 and the bottom number is 96. Prove: x = 45
It's a little blurry sorry. Please help me I have never understood two-column proofs and they don't make sense to me
Thank you

Answer 1

Hello!

You just have to solve the equation and justify each step along the way:

2x + 6, 96 Given
96 = 2x + 6 Vertical angles are congruent
90 = 2x Subtraction Property of Equality
45 = x Division Property of Equality

And that's all there is to it! I hope this helps you. (:
