Because of rules of geometry we know that a+b=180 degrees so we can add the equations together and set that equal to 180 and solve
6x-48+4x+38=180
subtract 38 from both sides and add 48 to both sides
then add like terms
10x=170
and divide by 10 to get
x=17
Answer:
the answer is 17 since you multiply a negative 5 by a negative which is positive 10 and add 7 to that its 17
