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 . . .

Q: What are the values of x and y if 7x plus 6y plus 20 equals 180?

a = 20 b = 60 c = 100

Combining like terms, 16x + 20 = 180 or 16x = 160 so that x = 10

3x + 2x - 20 = 180 5x - 20 = 180 Add 20 to both sides: 5x = 200 Divide both sides by 5: x = 40

Gathering like terms together, this can be rewritten: 9a = 180 Dividing both sides of the equation by 9: a = 20

28 plus 17 plus 25 plus 54 plus 20 plus 36 is equal to 180.

To solve this one, subtract 50 from 180 and you'll have your answer.

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

a + 3a + 5a = 180 9a =180 a = 20

a = 20 b = 60 c = 100

180/20=99*20=180

Combining like terms, 16x + 20 = 180 or 16x = 160 so that x = 10

3x + 2x - 20 = 180 5x - 20 = 180 Add 20 to both sides: 5x = 200 Divide both sides by 5: x = 40

Gathering like terms together, this can be rewritten: 9a = 180 Dividing both sides of the equation by 9: a = 20

28 plus 17 plus 25 plus 54 plus 20 plus 36 is equal to 180.

20 = 400

20 plus 20 equals 4020 plus 20 = 40
