I’m pretty sure the answer is capillaries from biology last year!
The equation given in the question is
(5x + 2)/2 = 2x - 1
5x + 2 = 2(2x - 1)
5x + 2 = 4x - 2
5x - 4x = - 2 - 2
x = -4
So the value of the unknown variable comes out to be -4. Yes your calculation is correct it seems from the answer that you have given. I hope i have been able to help you in this regard.Only be careful about the cross multiplication part.
There are 24 students in total.
6 own a cell,
the rest does not, 24 - 6 is 18, so 18 do not.
Multiplication property of equality
Step-by-step explanation:
We are given that the equation

We have to find the property which was applied to solve the equation.

Reason: Given
Multiply by -8/3 on both sides

By using multiplication property of equality.

After simplification
