What is... –9v + 1 = –8v − 7

v=8

Step-by-step explanation:

–9v + 1 = –8v − 7

Add 9v to each side

–9v+9v + 1 = –8v+9v − 7

1 = v-7

Add 7 to each side

1+7 = v-7+7

8 =v

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

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .
