Triangle = Equilateral Triangle
Therefore, all sides are equivalent to each other.
WORKING OUT:
5x - 22 = 4x - 10
5x - 4x = - 10 + 22
x = 12
CHECKING USING OTHER EQUATION COMBINATIONS:
4x - 10 = 3x + 2
4x - 3x = 2 + 10
x = 12
5x - 22 = 3x + 2
5x - 3x = 2 + 22
2x = 24
x = 24 / 2
x = 12
ANSWER:
x = 12
