Answer:
a) 4
Step-by-step explanation:
y = 3x
Plug it in: x - 2 (3x) = 10 --> x - 6x = 10 --> -5x = 10 --> x = -2
Therefore: y = 3(-2) --> y = -6
x - y = -2 - (-6) = 4
3x = y
x - 2(3x) = 10
x- 6x = 10
-5x = 10
x = -2
3x = y
3(-2) = y
y = -6
Therefore x is -2 and y is -6.
x - 2(3x) = 10
x- 6x = 10
-5x = 10
x = -2
3x = y
3(-2) = y
y = -6
Therefore x is -2 and y is -6.
