43/10 - 12/5x + 11/2 = 1/2(-18/5x + 6/5)

Do the stuff in parentheses first

43/10 - 12/5x + 11/2 = -9/5x + 3/5

Now we have to isolate the everything with an x in ine side, and the stuff without x (the variable) on the other

Do this by adding 12/5x to both sides of the equation to switch the -12/5x to the right side

43/10 - 12/5x + 12/5x + 11/2= -9/5x + 3/5 + 12/5x

43/10 + 11/2 = -9/5x + 3/5 + 12/5x

98/10 = 3/5x + 3/5

Now subtract both sides by 3/5 to switch the 3/5 to the left side

98/10 - 3/5 = 3/5x + 3/5 - 3/5

98/10 - 6/10 = 3/5x

3/5x = 92/10

Now divide both sides by 3/5

3/5x÷3/5 = 92/10 ÷ 3/5

x = (92×5)/(10×3)

x = 92/6

hope it helps, I double checked, it is correct.

just let me know uf you have any questions :)

Question 3 Unsaved
bazaltina [42]

Answer:

Step-by-step explanation:

DE given is

y''+8y'+15y=0, y(0)=0, y'(0)=1

Take Laplace on the DE

We get

s^2 Y(s) -sY(0) -y'(0)+8(sY(s)-y(0))+15Y(s) =0\\s^2 Y(s) -s(0) -1+8(sY(s)-0)+15Y(s) =0\\Y(s)(s^2+8s+15)-1=0\\Y(s) = \frac{1}{s^2+8s+15}

Simplify to get

Y(s) = \frac{1}{2}[ {\frac{1}{s+3} -\frac{1}{s+5} }]

Take inverse

y(t) = \frac{e^{-3t} -e^{-5t}}{2}
