How do I solve this equation?

Answer:
Step-by-step explanation:
1. Set 3x + 20 and 5x - 50 equal to each other
3x + 20 = 5x - 50
3x = 5x - 70
-2x = -70
x = 34
2. Once you've solved for x plug that in to 3x + 20 or 5x + 50
3(35)+ 20
105 + 20
125
3. After plugging in the x take that answer and subtract from 180 which will give you y
180 - 125 = y
55 = y
Answer
<em>you</em><em> </em><em>can</em><em> </em><em>solve</em><em> </em><em>this</em><em> </em><em>equation</em><em> </em><em>by</em><em> </em><em>finding</em><em> </em><em>the</em><em> </em><em>value</em><em> </em><em>of</em><em> </em><em>x</em><em> </em><em>and</em><em> </em><em>y</em><em>.</em><em> </em><em>here</em><em>,</em><em> </em><em>the</em><em> </em><em>answer</em><em> </em><em>is</em><em> </em><em>x</em><em>=</em><em>3</em><em>5</em><em>a</em><em>n</em><em>d</em><em> </em><em>y</em><em>=</em><em>5</em><em>5</em><em>.</em>
Step-by-step explanation:
here, we have,
i)3x+20=5x-50[being vertically opposite angle]
20+50=5x-3x
70=2x
70/2=x
thus,x=35.
ii) 3x+20+y=180[being straight angle]
3×35+20+y=180
125+y=180
y=180-125
thus, y=55
<h2>
hence, the value of x and y is 35 and 55.</h2>

Answer:
0. | 2
Step-by-step explanation:
I took (0.2) and made an equal sign and gave me 0. | 2
Minus both sides by 2m
Minus both sides by k
Divided both sides by 7
Answer:
x = -4
y = -12
Step-by-step explanation:
Since y is 3x,
3x = 2x - 4
On solving we get x as -4
Substitute x and we get y as -12
