Solve and show your work for the equation 3(4x – 2) = 9 + 2x + 5

Remember
you can do anyting to an equaiton as long as you do it to both sidess

distributive property
a(b+c)=ab+ac
commutativ property
a+b=b+a

distribute
3(4x-2)=12x-6

12x-6=9+2x+5
add 6 both sides
12x+6-6=9+6+5+2x
12x+0=20+2x
minus 2x
10x=20
divide 10
x=2

One unique triangle, because those angles add up to 180, and that's how many degrees there are in one triangle.

40 & 50 in the right corner are the complementary angles as when placed in a sum (added together) they make 90°
