I’m not sure what to do..
Arlecino [84]

Answer:

x=291/76

Step-by-step explanation:

Convert:

1/2x(6x+ 1/2)=-0.8x+16-1.2

Remove parenthesis and move terms:

3x+1/4=-0.8x+14.8

Collect the like terms and convert:

3x+0.8x=14.8-1/4

Subtract the fractions:

3.8x=74/5-1/4

Divide both sides by 3.8:

3.8x=291/20

x=291/76
