Math class was boring so I spend my time making this instead

solver.js

if (process.argv.length < 3)
	return console.log("No equation defined")

const equation = process.argv[2]

if (!equation.includes("=") || !equation.includes("x"))
	return console.log("Not a valid equation")
	
const firstHalf = equation.split("=")[0]
const secondHalf = equation.split("=")[1]

if (!firstHalf.includes("x")) {
	let temp = secondHalf
	secondHalf = firstHalf
	fistHalf = temp
}

for (let i=-1000000; i <=1000000; i++) {
	x = i/1000
	if (eval(firstHalf) == eval(secondHalf))
		console.log(`x=${x}`)
}
