How do I work out 2x + 37 = 8x + 7

You have to make sure that whatever you do to one side, you also do to the other.

2x + 37 = 8x + 7
2x + 37 - 2x = 8x + 7 - 2x
37 = 6x + 7
37 - 7 = 6x + 7 - 7
30 = 6x
30 / 6 = 6x / 6
5 = x
x = 5

Hope this helps! :)

$2x + 37 = 8x + 7\\
6x=30\\
x=5$

Solve the following initial-value problem: cos(x) dy/dx + sin(x) y - 1 = 0, y(0) = 1

Akimi4 [234]

Answer:

y= x + cosx

Step-by-step explanation:

$cosx\frac{\mathrm{d}y }{\mathrm{d} x}+(sinx)y-1=0\\cosx\frac{\mathrm{d}y }{\mathrm{d} x}+(sinx)y=1\\\frac{\mathrm{d}y }{\mathrm{d} x}+(tanx)y=secx$

now equation is in linear differential form

finding integrating factor;

I.F. = $e^{\int tanx dx} = e^{ln\ secx} = secx$

$y=\frac{1}{I.F}(\int Q dx + c)$

$y=\dfrac{1}{secx}(\int secx dx + c)$

$y=\int dx + c(cosx)\\y= x + c(cosx)$

using y(0) = 1

1 = 0 + c(cos 0)

c = 1

hence solution becomes

y= x + cosx
