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

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

5a + 2 = 7 subtract 2 from both sides: 5a = 5 divide both sides by 5: a = 1

a = 20 b = 60 c = 100

From your description, I get: a + b + c = 180b - 3a c = 5a You have two equations and three unknowns, which is unsolvable.

5a = 22 Divide both sides by 5: a = 4.4

If: -5a = 300 Then: a = -60

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

180x=179 divide by 180 on both sides and your left with .994444444....

5a+5=6a-7

(5a).7 = -23 7(5a) = -23 35a = -23 a = -23/35 a= -0.657 (3 d.p.)

Answer to: 5a + 1 = a - 3a = -1

4a + a = 25 add 4a and a 5a = 25 then divide 25 by 5 a = 5

5a = -5a + 5Add 5a to each side:10a = 5Divide each side by 10:a = 5/10 = 1/2

2a+5a+9a = 16a

what equals 180?

If: 5a-1+a = 11 Then: a = 2

The statement is false. 5a +6 = 5a + 30 Subtract 5a from both sides: 6 = 30 and that is plain and simple rubbish!

A= 2

divide 180 by 12 using factors

The supplement of an angle is (180) minus (the angle).Here we have an angle 'A', and we are told that: 2( 180 - A ) = 30 + 5( 180 - A ). We calculate:360 - 2A = 30 + 900 - 5A = 930 - 5A (clear parentheses)3A = 570 (Add 5A - 360 to both sides)A = 190 (Divide both sides by 3)Check:Its supplement is (180 - 190) = -102(-10) (?=?) 30 + 5(-10)-20 (?=?) 30 - 50-20 = -20 Yes !

7a + 4 = 5a + 7 7a = 5a + 3 2a = 3 a = 3/2

6a + 4 = 5a - 2 means that 6a - 5a = -2 - 4 which gives a = -6
