Step-by-step explanation:
3x - y = 74
4y = x
Replace x in the first expression by 4y
3x - y = 74 ➡ 3(4y) - y = 74
12y - y = 74
11y = 74
y = 74/11 we can use this to find x
4y = x
4 × 74/11 = x
296/11 = x
In the given equation the value of the x be a x = U*ky-y.
According to the statement
we have to find that the value of the x from the given statement.
So, For this purpose, we know that the
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
From the given information:
The given statement is
U=x+y/ky
now, rearrange the terms then
U*ky=x+y
U*ky-y = x
And then the value f the x become
x = U*ky-y.
So, In the given equation the value of the x be a x = U*ky-y.

OK. I used my calculator to evaluate sec(85 degrees).
My calculator doesn't have a "sec" button on it.
But I remembered that
sec of an angle = 1 / (cosine of the same angle) .
So I used my calculator to find cos(85), and then I hit the
" 1/x " key, and got 11.474, which I knew to be sec(85).
