Answer 2

Looks like you can assume it's a square, so AB and CD are equal to each other. So put
32= 2/3x - 10 and solve.

Answer 3

2/3x-10=32
multiply 2/3 by x
2x/3
2x/3 - 10-32
-10 does not contain the variable to solve so move it to the right side of the equation adding 10 to both sides
2x/3=10+32
Add 32 to 10 = 42
2x/3=42
multiply both sides by three
multiply 42 by 3
2x=126
divide by 2
2x/2 = 126/2 x=126/2
divide
x=63
