okay so you would do it like this
2x + (3 - x)
2x + 3 - x
x + 3
the answer would be x + 3
hope this helps!
Following PEMDAS, the parentheses comes first. Essentially, (3 - x) is times 1, which removes the parentheses. So 2x + 3 - x. Subtract the x first. This leaves x + 3.

Well it's easy 3_3
A linear pair are two given angles whose sum is equal to .
Let the exterior angle be represented by , and the three interior angles of the triangle be represented by , and .
Assume that the vertex angle is the linear pair to the exterior angle .
i.e + = (sum of angles on a straight line)
Thus,
i. + = (sum of two opposite interior angles is equal to an exterior angle)
⇒ = -
Also,
= -
But,
+ + = (sum of angles in a triangle)
⇒ = - ( + )
and
+ = -
ii. + + = (sum of angles in a triangle)
= - ( + )
+ =
