Mathematics

Answer:

Step-by-step explanation:

Strictly speaking, more info is needed before one can find "the answer." Your v = 7 + b has two variables (v and b). Which one do you want to solve for?

If for b, subtract 7 from both sides, obtaining v - 7 = b.

v = 7 + b has already been solved for v, so nothing remains to be done here.

X-4y=7 -6x-3y=12 how do i solve by substitution

Dafna1 [17]

Answer:

x = 15

y = 2

Step-by-step explanation:

X-4y=7 | ×6 |

-6x-3y=12 | ×1 |

6x - 24y = 42

-6x - 3y = 12

___________+

27y = 54

y = 54/27

y = 2

x - 4y = 7

x - 4(2) = 7

x - 8 = 7

x = 7 + 8

x = 15

Find the general solution of {y}''-3y=8e^{3t}+4sin(t) .

babunello [35]

Answer:

$y(x)=C_1e^{\sqrt3t}+C_2e^{-\sqrt3t}-\frac{4}{3}e^{3t}-sint$

Step-by-step explanation:

We are given that linear differential equation

$y''-3y=8e^{3t}+4 sint$

Auxillary equation

$D^2-3=0$

$D=\pm \sqrt3$

C.F= $C_1e^{\sqrt3t}+C_2e^{-\sqrt3}$

P.I= $\frac{8e^{3t}+4sin t}{D^2-3}$

P.I= $\frac{8e^{3t}}{9-3}+4\frac{sint }{-1-3}$

P.I= $e^{ax}{\phi (D+a)}$ and $P.I=\frac{sinax}{(\phi D)}$ where D square is replace by - a square

P.I= $-\frac{4}{3}e^{3t}- sint$

Hence, the general solution

G.S=C.F+P.I

$y(x)=C_1e^{\sqrt3t}+C_2e^{-\sqrt3t}-\frac{4}{3}e^{3t}-sint$
