Expert Solution
Step 1: Write the given differential equations

Given space that space the space differential space equations space
left parenthesis straight a right parenthesis space y apostrophe minus 5 y equals negative 5 t y cubed
open parentheses b close parentheses space x space fraction numerator d y over denominator d x end fraction plus 5 y equals 2 x squared y to the power of 4 space space comma space space y open parentheses 1 close parentheses equals 3
