10a+7b undefined variables cannot be determined
2s-2b= a+b+c-2b simplified that would be a+c-b.
b + a + b - a = 2b
(a + 2b)(a + 2b)
12c + 2b
In mathematics, when you add a number to itself, it is the same as multiplying that number by 2. Therefore, b + b is equal to 2b. This is known as the distributive property of multiplication over addition.
If a = 2b
10a+7b undefined variables cannot be determined
2s-2b= a+b+c-2b simplified that would be a+c-b.
b + a + b - a = 2b
(a + 2b)(a + 2b)
8a+2b
12c + 2b
=2b
2B Multiplied by 3 plus B = 7B. Here is how it's worked out. You start with 2B, multiply that by 3 and you get 6B. Now all you have to do is add the last B, therefore adding 1B to equal 7B.
a + 2b = c a = c - 2b
a-b+a-b+2b+a = 4a
