2a + 9 = 4a - 19 9 + 19 = 4a - 2a 28 = 2a a = 14
-1
2a+6b
9=4a+13 9-13=4a -4=4a -4/4=a -1=a a=-1
a is equal to 1.
2a + 9 = 4a - 19 9 + 19 = 4a - 2a 28 = 2a a = 14
4a + 1 - a =19, rewrite your question, 4a + -a + 1 =19, 3a + 1 =19, subtract 1 from each side 3a = 18, divide by 3, a =6
5a
If your problem looks like this: 4a-a=_ the answer is... 3a
7a-2b
3a - 2b
555
-1
It can do, for the right value of A
10
4a+3-a =12 4a-a = 12-3 3a = 9 a = 3
4a2 - 9a + 5 = 4a2 - 4a -5a + 5 = 4a(a - 1) - 5(a - 1) = (4a - 5)(a - 1)
