They are simple linear equations with one unknown, lets tackle them, one step at the time solving for the unknown:
4x - 2(x - 5) = x + 13
4x - 2x + 10 = x + 13
2x + 10 = x + 13
2x - x = 13 - 10
x = 3
that is the solution.
3(6 - x) - 4 = 5x + 2(7x + 3)
18 - 3x - 4 = 5x + 14x + 6
14 - 3x = 19x + 6
14 - 6 = 19x + 3x
8 = 22x
x = 8/22 = 4/11

Therefore your answer would be
A.1206 cm³
Multiply top equation by -2, then add equations so b drops out....solve for a...plug in a to get b
Answer:
If you take All of them and add them then you get 262 I dont really understand what your trying to say
Numerical, subtraction, s
