Question

How do I solve this equation?

Answer 1

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 2

you can solve this equation by finding the value of x and y. here, the answer is x=35and y=55.

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

hence, the value of x and y is 35 and 55.
