9=4a+13 9-13=4a -4=4a -4/4=a -1=a a=-1

It is 9

11a+9 = 4a+30 11a-4a = 30-9 7a = 21 Solution: a = 3

2a + 9 = 4a - 19 9 + 19 = 4a - 2a 28 = 2a a = 14

4a+3-a =12 4a-a = 12-3 3a = 9 a = 3

11a + 9 = 4a + 30Subtract 9 from both sides to get: 11a = 4a + 21Subtract 4a from both sides to get:7a = 21Divide both sides by 7 to get:a = 3And there's your answer: a = 3

4a - 9 = 27 4a = 36 a = 9

The answer to the problem of 13 equals -4x plus 9 is x equals -1.

The answer to the problem of 12X plus 13 equals 9 is x equals -1/3.

The answer to 1 over 2x plus 13 equals 9 is x equals -8.

13

13...... 9 plus 5 equals 14...... 14 minus 1 equals 13

x=(-9)

48

-13+4+(-8)= -9+(-8) = -9-8 = -17

4

That factors to (2a - 7)(2a + 9)

8+5 = 6+7 = 8+9 13 = 13 = 17 Can you rephrase? the question isn't too clear...

29

2a-6a+9-4a+9

x=-7/13

-13

x=30...9+30=39 then divide by 3 equals 13.

5x + 13
