5 times a number increased
1 answer:
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.
