7a

3a+5b+7a=

-7a + 3a = -4a

(7a=3)=(-a-5)=16

9a-a = 19+7a 8a = 19+7a 8a - 7a = 19 + 7a - 7a 1a = 19 a = 19

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

It is: 2a+5a = 7a when simplified

555

7A + 3

a + 3a - 2 + 3a. Add the a + 3a + 3a = 7a. You can't combine the -2 & 7a so the solution is: 7a - 2.

18

a + 18 = 7a a-a +18 = 7a-a 18 = 6a 18/6 = 6a/6 3 = a 3=a

9a + 1

7a-17 = 4a+1 7a-4a = 1+17 3a = 18 a = 6

7a-3

7a-2b

It is: 7a+1 when simplified

UM 6a? Can you be a little more specific maybe? But 6a plus a is 7a

a2 + 7a - 8a2 = 6a7 ∴ a2 + 7a - 8a2- 6a7 = 0 ∴ a + 7 - 8a - 6a6 = 0 ∴ 7 - 7a - 6a6 = 0 ∴ 6a6 + 7a - 7 = 0

Collect like terms: 9a -7a = 9 - 15, ie 2a = -6, so a = -3

-7a+2a+9 is also -5a+9. -5a+9=24. -5a=15. a=-3.

(7a + 35)/-7 = 7(a + 5)/-7 = -(a + 5) = (-a - 5)

6+7a+6b

7a + 6 = -36 Subtract 6 from both sides: 7a = -42 Divide both sides by 7: a = -6 a = -6

-7a-7b
