-7a - 10 = 20 -3a
-7a + 3a= 20 + 10
-4a=30
divide by negative 4
a=-7.5
-7x-7.5=52.5-10=42.5
-3x-7.5=22.5
20+22.5=42.5

What is 4a plus 3a-4 equals 10?
4a+3a-4 = 10 4a+3a = 10+4 7a = 14 a = 2
What is the answer to 4a - 5 equals 7a - 7?
4a - 5 = 7a - 7 -5 = 3a - 7 2 = 3a a = 3/2
What is 3a-7a plus 12 equals 32?
It's a linear equation in ' a '.When you see one of these, it often happens that curiosity overtakes you, and you begin to wonder about the numerical value of ' a ' that makes the equation true. Let's find out:3a - 7a + 12 = 323a - 7a = 20-4a = 20a = 20 / (-4) = -5The equation is true if ( a = -5 ).
How do you solve 4a-2 equals 7a-6?
4a-2=7a-6 4=3a a=4/3
2a-4y equals 3a - 8a-5y?
2a - 4y = 3a - 8a - 5y 7a = -ya = -(y/7)
What is 4a plus 3a-4 equals 10?
4a+3a-4 = 10 4a+3a = 10+4 7a = 14 a = 2
What is the answer to 4a - 5 equals 7a - 7?
4a - 5 = 7a - 7 -5 = 3a - 7 2 = 3a a = 3/2
What is -7a plus 3a?
-7a + 3a = -4a
Simplify a plus 3a-2 plus 3a?
a + 3a - 2 + 3a. Add the a + 3a + 3a = 7a. You can't combine the -2 & 7a so the solution is: 7a - 2.
What is 3a 7a simplified?
It is: 3a+7a = 10a simplified

7a-17 equals 4a plus 1?
7a-17 = 4a+1 7a-4a = 1+17 3a = 18 a = 6
How do you solve 4a-2 equals 7a-6?
4a-2=7a-6 4=3a a=4/3
What is 3a plus 5b plus 7a?
3a+5b+7a=
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.
Will you show me how to solve this problem 7a equals 2 times parenthesis a minus 10 parenthesis?
7a=2(-10)........................................answer is 20/7
2a-4y equals 3a - 8a-5y?
2a - 4y = 3a - 8a - 5y 7a = -ya = -(y/7)
