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
3a = 1a = 1/3 (a third)
If you mean -3a = 10-11 then a = 1/3
3a-9 = 6 3a = 6+9 3a = 15 a = 15/3 a = 5 Substitute a = 5 into 4a-1. 4a-1 =4(5)-1 =20-1 =19 Therefore, the value of 4a-1 is 19.

3a=1divide both sides by 3a=1/3
3a-2a = 1
a/(3a) = 1/3
3a^2 + 3a^2 = 6a^2 3a^2 - 3a^2 = 0 3a^2 x 3a^2 = 9a^4 3a^2 divided by 3a^2 = 1
3a = 1a = 1/3 (a third)
It is: 3a(1-4b)
