Answer:
x= 10
Step-by-step explanation:
A triangle always sums up to 180 degrees. (Remember this)
So, tha equation would be: 73+(4x-1)+(6x+8)= 180.
Step 1- Add common variables.
(4x+6x)+73+8-1= 180
10x+73+8-1= 180
Step 2- Add to simplify.
10x+(73+8-1)= 180
10x+80= 180
Step 3- Subtract 80 to both sides.
10x+80= 180
-80 -80
10x= 100
Step 4- Divide both sides by 10.
10x= 100
10 10
x= 10
