2x - y = 5 x + 3y = 7 what is the value of the y-determinant? a) 7 b) 9 c) 22

The two equations are,

1. 2 x- y=5

2. x + 3 y =7

To determine the y-determinant, we will evaluate

Option (B)→ 9 is correct y-Determinant.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

im pretty sure it would be 5 am, hope that , and give brainliest and guys if this is right then press the button and give 5 stars
