Answer:

Step-by-step explanation:
move the variable to the right(-2x) and change the sign(2x now) -3y=-12+2x then change the signs (-3y is 3y , -12 is 12 and then 2x becomes -2x again) then divide both sides of the equation by 3 so 12÷3=4 and -2x÷3=
then you're going to use the commutative property to reorder the terms . so your answer is 
Answer:
m<2 = 134°
m<3 = 46°
m<4 = 134°
Step-by-step explanation:
Because of vertical angles theorem, m<1 is congruent to m<3.
to find the m<2 and m<4 you need to subtract 46 from 180.
because m<2 and m<1 are adjacent and on a transversal line, they are equal to 180°
