3 - 
= 
- 7
First, simplify
to 
/ Your problem should look like: 3 - = - 7
Second, simplify to 
/ Your problem should look like: 3 - = - 7
Third, multiply both sides by 9 (the LCD of 9,3). / Your problem should look like: 27 - 2b = 3b - 63
Fourth, add 2b to both sides. / Your problem should look like: 27 = 3b - 63 + 2b
Fifth, simplify 3b - 63 + 2b to 5b - 63. / Your problem should look like: 27 = 5b - 63
Sixth, add 63 to both sides. / Your problem should look like: 27 + 63 = 5b
Seventh, simplify 27 + 63 to 90. / Your problem should look like: 90 = 5b
Eighth, divide both sides by 5. / Your problem should look like:
= b
Ninth, simplify to 18. / Your problem should look like: 18 = b
Tenth, switch sides. Your problem should look like: b = 18

Answer:
The answer in the attached figure
Step-by-step explanation:
step 1
Find the area of one blue square
step 2
Find the area of one orange triangle
Part 1)
Divide the total area by the area of one orange triangle
Part 2)
Divide the total area by the area of one blue square
Part 3)
Let
x----> the number of blue squares
y ------> the number of orange triangles
we know that
Construct a table and prove different values for x and for y
we have
x=2, y=3
Two blue squares and three orange triangles
Area of blue squares
Area of an orange triangles
so
the area total is
