A+a+3=a+13
2a+3=a+13
From here you want the variables on the same side, so you would subtract the a from a+13 and move it to 2a+3
2a+3=a+13
-a -a
a+3=13
Now you want the numbers on the same side
a+3=13
-3 -3
a=10

Step-by-step explanation:
To show your work, start by drawing 4 squares or circles. In each shape, split it into 3 parts. Now shade 8 parts out of all shapes. Your answer will be right in front of you. Hope this helped you. :)
Divide -22 by -0.4 and you’ll have your answer for k
Starting amount = g
Throughout the day 200 pounds is added and 1400 pounds is removed ( 700 x 2 = 1400)
Final weight is 1,100 pounds
g + 200 - 1400 = 1100
Simplify:
g - 1200 = 1100
Add 1200 to both sides:
g = 2300 pounds
