Answer:
x=19°
Step-by-step explanation:
Line n and l form a right angle. We know that because line m and l are parallel to each other and line n crosses through them as a vertical line.
Right angles always add up to 90°.
So, Angle 1 add Angle 2 equals 90°.
4x+9+x-14=90°
Collect the like terms:
Like terms are terms with the same variables and powers.
4x+x=5x
9-14= -5
Form an equation:
5x-5=90°
Do inverse operations to isolate x.
90+5=95°
95÷5=19° (We divide by 5 because, in algebra, when a number is next to a letter, it means times, so we have to do the opposite and divide).
So, x=19°
Hope this helps :)

Answer:
The first number is 10, and the second is 40.
Step-by-step explanation:
X is equivalent to 10, and the equation for this question is x + 4x = 50. Therefore, 5x = 50. If you divide both sides by 5, you get x = 10. This means the first number is 10, and since the second is 4 times that, 4*10 = 40. 40 + 10 = 50, to check.
