Question

If 5x + 3 = 23, what does 12x - 10 equal?

Answer 1

Let's solve the equation 5x + 3 = 23 for x:

Subtract 3 from both sides:

5x = 20

Divide both sides by 5:

x = 4

Now that we know x = 4, we can substitute it into the expression 12x - 10:

12x - 10 = 12 * 4 - 10 = 48 - 10 = 38

So, 12x - 10 equals 38.
