4a - 2.1 = 9a + 5.4 4a - 9a = 5.4 +2.1 -5a = 7.5 -a = 1.5 a = -1.5
10a + 3a - 4a = 9a
a= -4
It is the same as: 9a -4a = 5a
2a-5
4a - 2.1 = 9a + 5.4 4a - 9a = 5.4 +2.1 -5a = 7.5 -a = 1.5 a = -1.5
10a + 3a - 4a = 9a
9a + 4a = 26 13a = 26 a = 26/13 a = 2
a is equal to 1.
a= -4
It is the same as: 9a -4a = 5a
2a-5
so 5a = -20 making a = -4
2a+5
9a squared = 81a^2
