If 2-4=20 than x is equal to 12
<h3>-2(6+x)=18-3x</h3><h3>-12-2x=18-3x</h3><h3>-2x+3x=18+12</h3><h3>x=30</h3>
please mark this answer as brainlist
it would right to left , my teacher had a little saying , Left is Less
<span>2x-1/4(12x+4)=3
</span>⇒ 2x -1/4*(12x) -1/4*4= 3 (distributive property)
⇒ 2x -3x -1= 3
⇒ -x= 3+1
⇒ -x= 4
⇒ x= -4
<span>
Final answer: x=-4~

You can divide other shapes into triangles. Then you use what you know about the similar or congruent angles/sides (depending on your question) to determine congruency/similarity between other shapes.
