Answer:
Y = -2, X = 4
Step-by-step explanation:
When you first use the elimination method, you would multiply 2x-y = 10 by -2 so that you could get the 4x to be eliminated.
4x-3y = 22
(2x-y = 10)-2 = -4x + 2y = -20
When you add those 2 together you are left with -y = 2, which you divide by negative to get y = -2. Then you substitute -2 for y to solve for x. I substituted the bottom equation
2x - (-2) = 10
2x +2 = 10
2x = 8
Divide both sides by 2 to get x = 4.
The answer for the question is 20.25
Answer:
Ivan has 42 blue beads.
Step-by-step explanation:
We need to find how many blue beads Ivan has.
Blue beads = 6 times as many as red beans
b = 6r
r + b = 49
r + (6r) = 49
7r = 49
Divide both sides by seven to isolate r
r = 7
b = 6(7)
b = 42
