What’s the solution to this equation

2x+3=x-4

-7

Step-by-step explanation:

1. move the x to one side, (2x -1x)

2. new excuation is 1x+3=-4

3. minus 3 from each side (-4 - 3=-7)

4. -7÷1x= -7

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
