Jika2/3 daripada 30,berapakah nilainya

**7x - xy = -18 x = -4 ** First, fill the -4 in where the "x's" are.
7 (-4) - (-4) y = -18
Then, add the 28 over.
-28 + 4y = -18 +28 +28
**4y = 10 **
Then, get the variable by itself, so you would divide the 4 over.
4y = 10 ÷4 ÷4 y = 2.5 **

7 x − x y = − 18 an d x = − 4 7 ⋅ ( − 4 ) − ( − 4 ) y = − 18 − 28 + 4 y = − 18 4 y = − 18 + 28 4 y = 8 ∣ : 4 y = 2

The equation 7 x − x y = − 18 can be rearranged to find y = x 7 x + 18 ​ . By substituting x = − 4 , we find that y = 2.5 .
