7x + 6y + 20 = 180
We're just going to re-arrange it a bit, without changing anything:
Subtract (7x+20) from each side of the equation:
6y = -7x + 160
Divide each side by 6:
y = - 7/6 x + 80/3
This is exactly the same equation that you gave us in the question. But when we
write it in this form, we can see that it's the equation of a straight line that has a
slope of (- 7/6) and cuts the y-axis of the graph at (y = 80/3).
Every point on that line has a pair of coordinates ... one 'x' and one 'y' ... that are
a solution of the equation. And you know how many points there are on a line . . .

A plus b plus c equals 180 b equals 3a c equals 5a?
a = 20 b = 60 c = 100
3x plus 5x plus 10 plus 8x plus 10 equals 180?
Combining like terms, 16x + 20 = 180 or 16x = 160 so that x = 10
3x plus 2x-20 equals 180?
3x + 2x - 20 = 180 5x - 20 = 180 Add 20 to both sides: 5x = 200 Divide both sides by 5: x = 40
A plus 3a plus 5a equals 180?
Gathering like terms together, this can be rewritten: 9a = 180 Dividing both sides of the equation by 9: a = 20
What is 28 plus 17 plus 25 plus 54 plus 20 plus 36 equals?
28 plus 17 plus 25 plus 54 plus 20 plus 36 is equal to 180.
50 plus what equals 180?
To solve this one, subtract 50 from 180 and you'll have your answer.
What is the answer to a plus b plus c equals 180 b equals 3a c equals 5a?
a + b + c = 180 b = 3a c = 5a Substituting the values of b and c into the first equation. a + 3a + 5a = 180 or 9a = 180 so that a = 20 then b = 3a = 3*20 = 60 and c = 5a = 5*20 = 100
What is a plus 3a plus 5a equals 180?
a + 3a + 5a = 180 9a =180 a = 20
A plus b plus c equals 180 b equals 3a c equals 5a?
a = 20 b = 60 c = 100
What times 20 equals 180?
180/20=99*20=180
3x plus 5x plus 10 plus 8x plus 10 equals 180?
Combining like terms, 16x + 20 = 180 or 16x = 160 so that x = 10
3x plus 2x-20 equals 180?
3x + 2x - 20 = 180 5x - 20 = 180 Add 20 to both sides: 5x = 200 Divide both sides by 5: x = 40
A plus 3a plus 5a equals 180?
Gathering like terms together, this can be rewritten: 9a = 180 Dividing both sides of the equation by 9: a = 20
What is 28 plus 17 plus 25 plus 54 plus 20 plus 36 equals?
28 plus 17 plus 25 plus 54 plus 20 plus 36 is equal to 180.
What numbers equals 20 and what times what is 20?
20 = 400
What is 20 plus 20?
20 plus 20 equals 4020 plus 20 = 40
