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?
Oh, dude, it's like math time! So, when you add 3a and 7a together, you get 10a. It's like combining the apples and oranges of algebra. So, the simplified answer is just 10a. Easy peasy, lemon squeezy!

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)
