What value of x makes this equation true?

0.3x-7=0.8x+15

A. 52

B. - 44

C. - 16

D. 6

B. - 44

Step-by-step explanation:

0.3x-7=0.8x+15

first subtract 0.3x to the other side of 0.8x which will equal

-7=0.5x+15

Then subtract 15 to the othe side of the equal sign which will be

-22=0.5x

Then divide both sides of 0.5 (use calculator and put in - 22/0.5)

which will be - 44
