Well the thing is you didn't tell us which number but if it is 12 then i strongly believe that the answer is 3/9
Y= 3x + 1
Y = 3x + 3
Y= 3x + 4
Answer:
Given:
x-y=-4
2x+y=4
Step-by-step explanation:
x-y=-4
2x+y=4
add both the equation, we get
⇒ x-y=-4
2x+y=4
⇒3x=-4+4
⇒3x=0
⇒x=0
∴ to find the value of y, put the value of x in any one equation
⇒x-y=-4
⇒0-y=-4
⇒-y=-4
⇒y=4
∴ x=0, y=4
Typically Geometry. But it depends on your level.
