What is the value of x in the equation
x-2/3 + 1/6 =5/6

x = 4/3.

Step-by-step explanation:

x-2/3 + 1/6 =5/6

Add 2/3 and subtract 1/6 from both sides:

x - 2/3 + 2/3 + 1/6 - 1/6 = 5/6 + 2/3 - 1/6

x = 5/6 + 2/3 - 1/6

x = 5/6 + 4/6 - 1/6

x = 8/6 = 4/3.

To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.
