Patricia owned so many posters that she decided to sell 63 of them to her friends. After selling the posters, she still had 172 left. Write and solve an equation to find the number of posters p Patricia had originally
To find the number of posters Patricia originally had, we can set up an equation. Let's denote the original number of posters as "p". Patricia sold 63 posters to her friends, so the number of posters she had left is given by:
p - 63
According to the problem, after selling the posters, Patricia still had 172 left. So, we can write the equation:
p - 63 = 172
To solve this equation for "p", we need to isolate the variable. We can do this by adding 63 to both sides of the equation:
(p - 63) + 63 = 172 + 63
Simplifying, we get:
p = 235
Therefore, the original number of posters Patricia had was 235.
