a + 7b + 2c
11a+7b-(3b-2a)
100a2 - 49b2 is the difference of two perfect squares. Therefore, it is equal to the sum times the difference of the roots: (10a + 7b)(10a - 7b)
-58
6a + (7b - 4a - 8b) = (6a - 4a) + (7b - 8b) = 2a - b
2x + 7b is an expression. Since it is not an equation it cannot be solved. Furthermore, as an expression, there is no meaninful simplification, either.
-7a-7b
The given expression can be simplified to: 3b-a
a + 7b + 2c
It is: 19b+7b = 26b
It is: 7b+10 simplified
(-a-7b+5)4ab
11a+7b-(3b-2a)
9a + 7b *remember to look and understand the letters!*
If you mean: -3*(-2b-3)+7b then it is an algebraic expression that can be simplified to 6b+9+7b = 13b+9
100a2 - 49b2 is the difference of two perfect squares. Therefore, it is equal to the sum times the difference of the roots: (10a + 7b)(10a - 7b)
