16 - x = 27
x = -11
16 - x = 27
16 = 27 + x
16 - 27 = x
-11 = x

Answer:</h3><h3>X = 10</h3>
Step-by-step explanation:
(a) is the first one. 48 I would say 8 mins
(b) is the second one. 10 I would say is 96
Solve simultaneously.
4x - y = 8
6x + y = 2
Multiply top equation by 6, and bottom equation by 4, to eliminate x, so that we can find y.
~
24x - 6y = 48
24x - 4y = 8
Subtract top from bottom to form one equation.
~
-2y = 40
Therefore y is 20.
Put y back in to an equation, such as 4x - y = 8.
~
4x - 20 = 8
4x = 28
x = 7
Answer:
Mixture 1 and 2
Step-by-step explanation:
4/6 = 2/3
