You would set your equation up as basically f(x)-g(x), so:
(3x-4)-(x+2)
combine your like terms and you should have your answer:
2x-6
20 total balls:
5 are black
17 NOT yellow
12 NOT green
20-17 = 3
20-12 = 8
5 Black + 3 yellow + 8 green = 16 balls
20 total balls - 16 balls = 4 blue balls
Ewa has 4 blue balls.
Answer:
Y=-3/4x + 10
Step-by-step explanation:
Answer:
x = -1 and y = 18
Step-by-step explanation:
Given the system of equations
y + 8x = 10... 1
2y - 4x = 40 ... 2
From 1; y = 10-8x
Substitute into 2;
2(10-8x) - 4x = 40
20 - 16x - 4x = 40
20 - 20x = 40
-20x = 40 - 20
-20x = 20
x = -1
Recall that y = 10-8x
y = 10 - 8(-1)
y = 10 + 8
y = 18
therefore your answer is x = -1 and y = 18
2/54 is the answer I think
