I have worked that on paper
(2x-15) + 11x = 180
Combine your like terms in get
13x - 15 = 180
Add 15 on both sides
13x - 15 = 180
+15 + 15
13x = 195
Divide each side by 13 and get
x = 15
Answer:
x=2y=6
Step-by-step explanation:
x+2y=-2y+6+2y
Using proportions, it is found that the value of a is of 3.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, a 180º angle has a measure of
radians. What is the measure of a 540º angle? The <em>rule of three</em> is given by:
180º -
rad.
540º - x
rad.
Applying cross multiplication:
180x = 540.
x = 540/180 = 3.
The value of a is of 3.
