I️ have tons of hw ! if 8 is added to twice a number and there some is multiplied by five the result is the same as if the number is multiplied by -8 and four is added to the product. what is the number

5(2x +8) = -8x + 4

Use distributive property:

10x +40 = -8x + 4

Subtract 40 from each side:

10x = -8x -36

Add 8x to each side:

18x = -36

Divide both sides by 18:

x = -36 / 18

x = -2

The number is -2

the answer is c. hope this !

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
