Question one -40 + 3x = x + 14

x = 27

Step-by-step explanation:

The first thing we want to do in this algebraic expression is to remove the known number from the side with the largest x value. In our case, it's 40, and the way we remove it is by adding or subtracting from both sides, since our's is negative we'll add it to both sides.

- 40 + 3x = x + 14

+40                +40

3x = x + 54

Now that we have put the two common numbers together were going to add or subtract the smaller x value on both sides, here it's x.

3x = x + 54

-x    -x

2x = 54

This is the last step in finding our solution, here we want to divide both numbers by the number next to x, which is 2.

2x / 2 = x

54 / 2 = 27

Now that we have divided both numbers we know that our answer is

x = 27

Hope this helps, good luck with the rest of your day :)

answer is 144

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
