Opposite angles are equal


\\ \sf\longmapsto 2(x+10)=3x-30


\\ \sf\longmapsto 2x+20=3x-30


\\ \sf\longmapsto 3x-2x=30+20


\\ \sf\longmapsto x=50

Answer:

x = 50

Explanation:

→ Make the equations equal to each other

2 ( x + 10 ) = 3x - 30

→ Expand brackets

2x + 20 = 3x - 30

→ Minus 3x from both sides

-x + 20 = -30

→ Minus 20 from both sides

-x = -50
