How many solutions does the equation 5x + 3x − 4 = 10 have? zero one two infinitely many

I believe that it has two solutions

The given equation has just one solution

Step-by-step explanation:

To find the solution to the problem given, we will follow the steps below;

5x + 3x - 4 = 10

We will first start by simplifying

8x - 4 = 10

Add 4 to both-side of the equation

8x - 4 + 4 = 10 + 4

8x = 10

Divide both-side of the equation by 8

8x/8 = 10/8

At the left-hand side of the equation, 8 will cancel-out 8 leaving us with just x while at the right-hand side of the equation 10 will be divided by 8

x=1.25

Therefore the given equation has just one solution

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
