The resulting concentration of the final solution would be dependent on the masses of each solution. I cannot specifically calculate for the resulting concentration since the given values are incomplete. You can use the following equation:

Final concentration = C1M1 + C2M2 / (M1 + M2)

(This is a little difficult but I've got it)

((x - 45)/12) + 20 = 5(32 - x)

I know it’s not -2 please help!!
hjlf

Answer:

\boxed { - 4}

Step-by-step explanation:

Substitute y = x-4 in the first equation.

3x - 2(x - 4) = 4

Distribute -2 in the expression.

3x - 2x + 8 = 4 \\ x = 4 - 8 \\ x =  - 4

Because we only want to find the value of x.

Therefore the answer is -4.
