OK. Then let's just give the other letters different names.
Instead of T = p d / 2x
let's write Tiger = pig dog / 2x
Multiply each side by 2x : 2x Tiger = pig dog
Divide each side by Tiger : 2x = pig dog / Tiger
Now divide each side by 2 : x = pig dog / 2 Tiger
Of course you would not hand it in on a homework sheet like that. You would change it back to **x = p d / 2 T ** .
When there's more than one letter, and you just have to solve for one variable, you can just solve it like you would any other equation. Treat the other variables like numbers and add, subtract, multiply, and divide them to both sides of the equation in order to isolate the variable you want to solve for.
t = 2 x p d t ∗ 2 x = 2 x p d ∗ 2 x 2 t x = p d 2 t 2 t x = 2 t p d x = 2 t p d
To solve for x in the equation t = 2 x p d , we rearranged it to find x = 2 t p d . This allows you to compute x using the known values of p , d , and t .

Jawaban:soalBerapa nilai dari n(X gabung (Y irisan Z komplemen)) pada diagram venn tersebut? 1. Cari (Y irisan Z komplemen)- Z komplemen adalah semua elemen di luar lingkaran Z.- (Y irisan Z komplemen) adalah irisan Y dengan area di luar Z. Dari diagram, ini adalah area 'b' dan '7'.- Jadi, n(Y irisan Z komplemen) = b + 7 2. Cari (X gabung (Y irisan Z komplemen))- (X gabung (Y irisan Z komplemen)) adalah gabungan X dengan hasil sebelumnya. Ini mencakup semua area di X (yaitu, 'a', '3', '8', '6') dan area 'b' dan '7' dari (Y irisan Z komplemen).- Jadi, n(X gabung (Y irisan Z komplemen)) = a + 3 + 8 + 6 + b + 7 3. Kita tahu:- n(X) = 21, maka a + 3 + 8 + 6 = 21, sehingga a + 17 = 21, maka a = 4- n(Y) = 26- n(Z) = 29 4. Substitusikan nilai a ke dalam persamaan:- n(X gabung (Y irisan Z komplemen)) = 4 + 3 + 8 + 6 + b + 7 = 28 + b 5. Cari nilai b- Kita tahu n(Y) = b + 6 + 8 + 7 = 26- b + 21 = 26- b = 5 6. Hitung hasil akhir:- n(X gabung (Y irisan Z komplemen)) = 28 + b = 28 + 5 = 33 tidak jawaban yang sesuai perhitungan caranya
