Answer:

x=6, AB=13, y=10, AD=13, P=46

3x-5=x+7

2x=12

x=6

AB: 3(6)-5= 13

2y-7=y+3

y=10

AD: 10+3=13

Perimeter= 13+13+10+10=46

1. 3x + 12 = 8x - 18
Ray Of Light [21]

Answer:

  1. given
  2. addition property of equality
  3. addition property of equality
  4. division property of equality
  5. symmetric property of equality

Step-by-step explanation:

In step 2, -3x was added to both sides in accordance with the addition property of equality.

The same property lets you add 18 to both sides, as in step 3.

The division property of equality lets you divide both sides of the equation by 5. (Or, the multiplication property lets you multiply by 1/5.)

Swapping sides of the equal sign is allowed by the symmetric property of equality.
