What is -7a plus 3a?
-7a + 3a = -4a
What is 4a plus 3a?
4a + 3a = (4 + 3)a = 7a
7a-17 equals 4a plus 1?
7a-17 = 4a+1 7a-4a = 1+17 3a = 18 a = 6
3a 4b equals 7a 4b?
Clearly, there are some signs missing. So let's try the four possibilities for the second terms: 1. + and + 3a + 4b = 7a + 4b Subtract 4b from each side: 3a = 7a Subtract 3a from each side: 0 = 4a Answer : a = 0, b indeterminate (ie can have any vaue). 2. + and - 3a + 4b = 7a - 4b Subtract 4b from each side: 3a = 7a - 8b Subtract 7a from each side: -4a = -8b or 4a = 8b Answer: a = 2b 3. - and - 3a - 4b = 7a - 4b Add 4b to each side: 3a = 7a Subtract 3a from each side: 0 = 4a Answer : a = 0, b indeterminate (ie can have any vaue). 4. - and + 3a - 4b = 7a + 4b Add 4b to each side: 3a = 7a + 8b Subtract 7a from each side: -4a = 8b or 4a = -8b Answer: a = -2b Can't do better than that with the information available.
What is 7a plus 3b-4a-5b?
3a - 2b
What is -7a plus 3a?
-7a + 3a = -4a
What is 4a plus 3a?
4a + 3a = (4 + 3)a = 7a

What is the answer to 4a - 5 equals 7a - 7?
4a - 5 = 7a - 7 -5 = 3a - 7 2 = 3a a = 3/2
7a-17 equals 4a plus 1?
7a-17 = 4a+1 7a-4a = 1+17 3a = 18 a = 6
What is 4a plus 3a-4 equals 10?
4a+3a-4 = 10 4a+3a = 10+4 7a = 14 a = 2

How do you solve 4a-2 equals 7a-6?
4a-2=7a-6 4=3a a=4/3
What is -7a - 10 equals 20 - 3a?
-7a - 10 = 20 -3a-7a + 3a= 20 + 10-4a=30divide by negative 4a=-7.5-7x-7.5=52.5-10=42.5-3x-7.5=22.520+22.5=42.5
What is 7a plus 3b-4a-5b?
3a - 2b
What is 4a minus b plus 3a plus b?
7a-2b
(4a-5) plus (3a plus 6)?
It is: 7a+1 when simplified
