Let's solve your system by substitution.
−3x+y=−2;y=4x
Rewrite equations:
y=4x;−3x+y=−2
Step: Solvey=4xfor y:
y=4x
Step: Substitute4xforyin−3x+y=−2:
−3x+y=−2
−3x+4x=−2
x=−2(Simplify both sides of the equation)
Step: Substitute−2forxiny=4x:
y=4x
y=(4)(−2)
y=−8(Simplify both sides of the equation)
Answer:
x=−2 and y=−8

The possible ways to get a sum of 4 are (1, 3), (3, 1), (2, 2) .
There are a total of 6 * 6 = 36 possible outcomes when 2 dice are rolled.
Thus the probability of the sum being 4 = 3 / 36 = 1/12 (answer).
