Answer:
x=-4/3
Step-by-step explanation:
3x-12=12x
3x-12x=12
-9/-3=12/-3
then -3 cancels
3x/3=-4/3
then 3 cancels 3
so x=-4/3
Answer:
x=2
Step-by-step explanation:
Since rectangles have 90* angles at each corner, we can say the two equations in the corner equal to 90*
so,
13x+34+10x+10=90
23x+44=90
23x=46
x=2
