5 times a number increasedby 18 is the same as 36 more
than times 4 times the
number. Find the number.

Answers

Answer:

18

Step-by-step explanation:

Let's make this information into an equation.

We'll use 'x' whenever the problem says "a number".

Equation:

5x + 18 = 36 + 4x

How did I get to this equation?

  • 5 times a number means 5 multiplied by x
  • increased by 18 means to add 18
  • is the same as means equals
  • 36 more than means to add 36
  • 4 times the number means 4 multiplied by x

Now, let's solve.

Solve:

5x + 18 = 36 + 4x

Subtract 18 on both sides:

5x + 18 = 36 + 4x

     -18     -18

5x = 18 + 4x

Subtract 4x on both sides:

5x = 18 + 4x

-4x        -4x

x = 18

Therefore, "the number" is 18.
