We know that y is equal to x-2. We can just substitute x-2 for y since y is equal to it.

10x- 9(x-2)=24

Distribute.

10x- 9x+18= 24

x+18= 24

Subtract 18 on both sides.

x= 6

Now, plug in x.

y= (6)-2

y= 4

We can check this to see if this works:

4= 6-2, 4=4

10(6)- 9(4)= 24

60-36= 24, 24=24

x=6 and y=4

I hope this helps!

Step-by-step explanation:

Simplifying the expression involve reducing the number of terms to minimum and making the expressions in standard form.

This may involve addition, subtraction and multiplication of variables.

Given expression is:

$5x(3x+2)$

Distributing 5x will give us:

$= 5.3.x.x + 5.2.x\\=15x^2+10x$

Well, create an equation.

From there you would go to Desmos.com and find out. The answer is 4,28.
This means it's the fourth term and the number is 28.
