3a2

4a + 3a = (4 + 3)a = 7a

Add them together: 3a+4a-a = 6a

10a + 3a - 4a = 9a

4a+3a-4 = 10 4a+3a = 10+4 7a = 14 a = 2

"a" plus "3a" is equal to 4a. (3a+a=4a). You already have 3 "a's" and then you add another "a."

10a − 3 − 4a

-7a + 3a = -4a

14a - 4a + 5a - 3a = 12a

3a + 15 = 4a Subtract 3a from both sides 15 = a So a is 15.

11

3a + 11 = 7a - 13 subtract 3a from each side 3a - 3a + 11 = 7a - 3a - 13 11 = 4a - 13 add 13 to each side 11 + 13 = 4a - 13 + 13 24 = 4a divide each sides integer by 4 24/4 = (4/4)a 6 = a -------------check in original equation 3(6) + 11 = 7(6) - 13 18 + 11 = 42 - 13 29 = 29 ----------------checks out
