How to identify and combine like terms?

sample problem 9b + 3a - a + 6+ 2b + 4 terms would be each number or number plus a variable separated by an operation symbol (+ or -) like terms would be 9b and 2b, 3a and -a, and 6 and 4 simply add 9b + 2b (which is 11b) 3a-a (which is 2a) and 6 + 4 (which is 10) your answer would then be 11b + 2a + 10 hope that helped

What is 3a plus 2b?

3a + 2b is an expression in algebra. If you make 3a + 2b equal to something then you can find the values of "a" and "b" Lets say you make 3a + 2b equal to 23 3a + 2b = 23 Now find "a" and "b" to make this equation true... 3(5) + 2(4) = 23 15 + 8 = 23 23 = 23 Correct So in this case a=5 and b=4


What is 3a plus 2b when 5 is a and 2 is b?

7


3a plus 2b equals 4 and b equals 7?

3a + 2b = 4If b = 7, then3a + 2(7) = 43a + 14 = 4Subtract 14 from each side:3a = -10Divide each side by 3:a = -10/3


What is 3a plus 4 plus b plus 2a plus 5 plus b?

The idea here is to combine terms that have the same variable (or, in more complicated cases, the same combination of variables). For example, 3a + 2a is the same as 5a.

What is the solution of a 5a-5 equals 7 plus 2a?

5a - 5 = 7 + 2a ( subtract 2a from both sides) 3a - 5 = 7 (add 5 to both sides) 3a = 12 ( divide both sides by 3) a = 4


Can you solve this 3a plus 4 divided by 12 minus 5 over 3 equals 2a minus 1 divided by 2 need the steps?

(3a+4)/12 - (5/3) = (2a-1)/2Multiply each side by 12:(3a+4) - (20) = 6 (2a-1)Eliminate the parentheses:3a + 4 - 20 = 12a -63a -16 = 12a -6Add 6 to each side:3a -10 = 12aSubtract 3a from each side:-10 = 9aDivide each side by 9:-10/9 = a


Could you work out these simultaneous equations 2a plus 3b equals 13 and a plus 2b equals 8 and show me the working out please because I'm really stuck?

I think you have 2a + 3b = 13 2b = 8 If so, the second equation gives, by dividing both sides by 2, b = 4 then plug in b = 4 in first equation 2a + 3(4) = 13 2a + 12 = 13 2a = 1 a = 1/2


What is 3a plus 2 plus 3a plus 2?

It is 6a + 4


How do you write four times the sum of 2a and b increased by twice the sum of 6a and 2b?

4(2a+b) + 2(6a+2b) Working this out it is: 8a + 4b + 12a + 4b = 20a + 8b or 4(5a+2b).
