Question

N is the inventor of and nq = 2x, and nr = 3x-2. Find ns.

a) 3x
b) 4x-2
c) x+2
d) 2x-3

Answer 1

To find ns, substitute the given values of nq and nr into the equation and solve for x. Then substitute x back into the equation to find ns, which is equal to 4.

Step-by-step explanation:

To find ns, we need to substitute the given values of nq and nr into the equation. Let's start by substituting nq into the equation:

ns = 2x

Now, let's substitute nr into the equation:

ns = 3x - 2

Since both equations represent ns, we can set them equal to each other and solve for x:

2x = 3x - 2

To isolate the variable, let's subtract 2x from both sides:

2x - 2x = 3x - 2 - 2x

Simplifying:

0 = x - 2

Finally, let's solve for x by adding 2 to both sides:

0 + 2 = x - 2 + 2

Therefore, the value of x is 2. Now we can substitute x back into either equation to find ns. Let's use the first equation:

ns = 2x = 2(2) = 4

So, the value of ns is 4.
