Justify each step in solving the equation 7x = 2(x - 5) by writing a reason for each statement. drag the answers into the boxes to correctly complete the proof. statement reason 1. 7x = 2(x - 5) 2. 7x = 2x - 10 3. 5x = -10 4. x = -2 division property of equalitygivensubtraction property of equalitydistributive property

Let's solve this equation and put the words with it along the way.

1) 7x = 2(x - 5) [given: this is, well, the problem]

2) 7x = 2x - 10 [Distributive Property: 2 was distributed throughout (x-5)]

3) 5x = -10 [Subtraction Property of Equality: We subtracted 2x on both sides]

4) x = -2 [Division Property of Equality: We divided both sides by 5]

Hope this helps!

answer: a and b

step-by-step explanation:

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
