Emerson Massey · Answer 1

X = 1 which means Y = - 1

Step-by-step explanation:

2x - y = 3

y = - x

Sub for y

2x + x = 3

Add the x's

3x = 3

Divided by 3

x = 1

Mayra Molina · Answer 2

These are simultaneous equations. They have to be solved like this:

2x-y=3 - y=3-2x 2x-3 = - x

y = - x y = - (3-2x) 3x = 3

y=2x-3 x=1

Step-by-step explanation:

The value of x equals to 1

2x - y = 3y = - xWhat's the value of x?

2x - y = 3

y = - x

What's the value of x?
