Step-by-step explanation:
Exterior Angle Theorem = the exterior angle of a triangle is equal to the sum of the two opposite interior angle
Thus, 2x+6+36=4x-18
2x+42=4x-18 add 18 to both side
2x+60=4x minus 2x
60=2x
x=30
The part the it is multiplying by the placholder (not adding)
example
2+4x
4 is placeholder, 2 is not
x and y are placeholders
5/3 is not
5/3 is the coefient
