4a+3a-4 = 10 4a+3a = 10+4 7a = 14 a = 2
4a - 5 = 7a - 7 -5 = 3a - 7 2 = 3a a = 3/2
6-3a**2+7+4a-5a+18 3a**2-1a+31
4a-2=7a-6 4=3a a=4/3
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
4a+3a-4 = 10 4a+3a = 10+4 7a = 14 a = 2
3a2
4a - 5 = 7a - 7 -5 = 3a - 7 2 = 3a a = 3/2
(a + 2)(3a - 2)
It is 4a2.
