Solve for x:<br><br> 3x – 14 = -5x + 2
dalvyx [7]

Hello there!

3x-14=-5x+2

Add 5x to both sides:

3x-14+5x=-5x+2+5x\\8x-14=2

Add 14 to both sides:

8x-14+14=2+14\\8x=16

Now divide both sides by 8:

\frac{8x}{8}=\frac{16}{8}

In our last step, we will simplify 16/8:

\frac{16}{8}=2\\ x=2

Hope this helps!

Find the general solution, y(t), which solves the problem below, by the method of integrating factors.
Sonbull [250]

The general solution, y(t), which solves the problem by the method of integrating factors is; y = ¹/₂₁t⁴ + (1/t)c₁t^(⁴/₅)

<h3>How to solve differential equations?</h3>

We want to find the general solution of;

5t(dy/dt) + y = t⁴

We will divide through by 5t to get;

(dy/dt) + y/5t = t³/6

Using Integration factor, we have;

u(t) = e^∫(¹/₅t) dt = t^(¹/₅)

Thus, we now have;

[t^(¹/₅)](dy/dt) +  [t^(¹/₅)]y/5t = [t^(¹/₅)]t³/6

Completing this with a differential calculator gives us the general solution as;

y = ¹/₂₁t⁴ + (1/t)c₁t^(⁴/₅)
