3(2x)=4x+4
do the bracket first
(3)(2x)= 6x
6x= 4x+4
move 4x to the other side
sign changes from +4x to -4x
6x-4x=4x-4x+4
6x-4x= 4
2x= 4
divide by 2
2x/2=4/2
x=2
Answer: x= 2
Two corresponding angles are congruent implies the two lines are parallel. This is the definition of the converse of the corresponding angles theorem.
X = 79/16, D : 4.9375 :) hope this helps uu!
