Red and gray bricks were used to build a decorative wall. The number of red bricks and the number of gray bricks was . There were 175 bricks used in all. How many red bricks were used? (1 point) Responses 25 25 125 125 50 50 35

Let's set up an equation to solve this problem:

Let "R" represent the number of red bricks used and "G" represent the number of gray bricks used.

We know that the total number of bricks used is 175, so we can write the equation:

R + G = 175

However, we don't have enough information to solve for the values of R and G individually.
