The deltoid, also known as the kite shape is a quadrilateral whose four sides can be grouped into two pairs of equal-length sides that are adjacent to each other.
3a=b
7a-14=b+6
this is a system of two equations
Take value for "b" from the 1st equation and substitute for b into 2nd equation

The deltoid, also known as the kite shape is a quadrilateral whose four sides can be grouped into two pairs of equal-length sides that are adjacent to each other.
3a=b
7a-14=b+6
this is a system of two equations
Take value for "b" from the 1st equation and substitute for b into 2nd equation
7a - 14 = 3a + 6
solve for a
7a - 3a = 14 + 6
4a = 20
a = 5
b = 3a = 3*5=15
You should never assume anything unless it is explicitly marked or stated. With the information provided, a and b can't be uniquely determined.
Now if there is something that says this is a kite shape, or that MO is a perpendicular bisector of LN, then you can show that LM = MN and LO = NO.
Use that to create two equations involving a and b.
3a = b
7a - 14 = b + 6
Substitute for b in the second equation:
7a - 14 = 3a + 6
4a = 20
a = 5
Then solve for b:
b = 3a
b = 3(5)
b = 15
They hold no value except intrinsically.
