You just have to add the 41 and 87 with the 542
The value of x in the given expression is; x = wz/y
<h3>How to change subject of formula?</h3>
We are given the expression;
w/x = y/z
Now, we want to find the value of x which means we want to make x the subject of the formula. Thus;
Multiply both sides of the given expression by x to get;
(w/x)*x = (y/z)*x
⇒ w = xy/z
Now, multiply both sides by z/y to get;
w(z/y) = (xy/z) * (z/y)
wz/y = x
Thus, the value of x in the given expression is;
x = wz/y
The correct question is;
If w/x = y/z, then what is the value of x

The polynomial would be 2x+5.
We bring down the first number inside the box, 2, unchanged.
_______
-1| 2 7 5
_______
2
Now we multiply that 2 by the number outside, -1:
_______
-1| 2 7 5
<u> -2
</u> 2
Now we add the two numbers in the middle column:
________
-1| 2 7 5
<u> -2 </u>
2 5
Multiply the 5 we brought down by the -1:
________
-1| 2 7 5
<u> -2 -5
</u> 2 5
Add the numbers in the last column:
________
-1| 2 7 5
<u> -2 -5
</u> 2 5 0
The 3 numbers under the box represent the coefficients of x² and x, as well as the constant. When we finish, we no longer have an x², but start at the next level down, which would be x. 2 would be the coefficient of x and 5 would be the constant, with 0 remainder.
The answer is 9x^3-6x^2+3x
