Ответ:
first, collect like terms:
5x-13=22
next move the constant to the right-hand side and change its sign:
5x=22+13
then add:
5x=35
lastly divide both sides of the equation by 5:
and you get x=7
hope this helps!! :))
Ответ:
x = 32
Step-by-step explanation:
Triangle angle sum theory states that the interior angles of a triangle sum to 180. Add all three angles up and set equal to 180 to solve.
33+ 37 + (3x+14) = 180. Combine like terms
84 +3x = 180. Subtract 84 from both sides.
3x = 96. Divide both sides by 3.
X = 32
