What is the solution to the system of linear equations below? 2/5x−y=6 −2x+5y=−30 Select one: A. (-13, 14) B. (-5, -8) C. no solution D. infinitely many solutions
Answers
Answer:
D. Infinitely many solutions
Step-by-step explanation:
[tex]-\frac{2}{5}x-y=6 | -2x+5y=-30[/tex]
1.Since neither equation contains an isolated. However, we can isolate -y in the first equation by adding [tex]\frac{2}{5}x[/tex] to both sides.
Like this: [tex]\frac{2}{5}x-\frac{2}{5}x-y=6-\frac{2}{5}x[/tex]
ending up with [tex]y=6-\frac{2}{5}x[/tex]
2.Now, we can change y to a positive y. By doing so, we divide -y by the entire equation.
Like this [tex]\frac{-y=6-\frac{2}{5}x }{-y}[/tex]
Ending with [tex]y=-6+\frac{2}{5}x[/tex]
3.Now, we can plug the expression [tex]-6+\frac{2}{5}x[/tex] into the second equation as a substitute for y, and solve for x. Then, we can use x to calculate y.
Like this [tex]-2x+5(-6+\frac{2}{5}x)=-30\\ -2x-30+2x=-30\\[/tex]
4. Since -2x+2x would cancel out and leave -30=-30. This is true because we know -30 equals -30 with no variable in sight.

Step-by-step explanation:
1.
Start with -$126.89
Small deposit: x (add)
Large deposit: 3.5x (add)
Withdrawal: $25 (subtract)
-126.89 + x + 3.5x - 25 =
= -151.89 + 4.5x
= 4.5x - 151.89
Answer: 4.5x - 151.89

Start with $350
Small withdrawal: x (subtract)
Large withdrawal: x + 50 (subtract)
Deposit: $75 (add)
350 - x - (x + 50) + 75 =
= 350 - x - x - 50 + 75
= -2x + 375
