2a + 3a + 4 = 5a + 4
4a + 3a = (4 + 3)a = 7a
a = 3a + 4 0 = 2a + 4 2a = -4 a = -2
3a + a = 4a Example: a = 5 (3x5) + 5 = 15 + 5 = 20 = 4 x 5
3a + 4 = 4a - 3 4 = a -3 (subtract 3a from each side) 7 = a (add 3 to both sides) a = 7
It is 6a + 4
2a + 3a + 4 = 5a + 4
(3a - 4)(3a - 4)
It can be simplified to: 3a^2 +10a+7 or factored as (3a+7)(a+1)
4a + 3a = (4 + 3)a = 7a
7a
4a+3a-4 = 10 4a+3a = 10+4 7a = 14 a = 2
7a minus 2, if "3a-2" means 3a minus 2. 3a plus 1 and 1-3rd in parenthesis times 3a, if "3a-2" means 3a squared. a plus 3a squared plus 3a = 1-3rd times 3a plus 3a times 3a plus 1 times 3a = 3a plus 1 and 1-3rd in parenthesis times 3a
a = 3a + 4 0 = 2a + 4 2a = -4 a = -2
3(a+4) = 3a+12
3a + a = 4a Example: a = 5 (3x5) + 5 = 15 + 5 = 20 = 4 x 5
a is equal to 4
