Question

Maria is 19 years old. Her age is 4 more than 3 times some number, x.

Answer 1

x=5

19-4=15
15/3=5

Or

5 x 3 = 15
15 + 4 = 19

Answer 2

Answer: x = 5

Explanation:

We can set up an equation to solve for x:

3x + 4 = 19

We can subtract 4 from both sides:

3x = 15

We can divide both sides by 3:

x = 5
