Question

if an angle is 6° less than twice its supplement how much does each angle measure

Answer 1

Your answer is here

Let one angle be x°and another angle be (2x-6)°
A/q,

$x + 2x - 6 = 180 \\ 3x = 180 + 6 \\ x = \frac{186}{3} \\ x = 62$
one angle = 62°
and another angle = (2×62-6)°
= (124-6)°
= 118°
