Consider the following pattern: 2 = 4, 3 = 5, 1 = 3, 5 = 7, 4 = 7, 2 = 5, 7 = 9, 5 = 9, 3 = 7. Solve for (4) + 8 - (7).

Steps to Solve
-
Find the value of (4) Look at the patterns provided. From the first column $2 = 4, 5 = 7, 7 = 9$. We can see that the right-hand side of the equation is the left-hand side plus 2. Therefore, $4 = 4 + 2 = 6$.
-
Find the value of 8 From the second column $3 = 5, 4 = 7, 5 = 9$. We can see that the right-hand side is the left-hand side plus 2 and then multiply by 1.5, or $3 = 23 -1, 4 = 24 -1, 5 = 25 - 1 $. Therefore, $8 = 28-1 = 16 - 1 = 15$.
-
Find the value of - From the third column $1 = 3, 2 = 5, 3 = 7$. We can see that the right-hand side is the left-hand side multiplied by 2 and add 1. Therefore, $7 = 2*7 - (-1) = 14 - (-1) = 15$.
-
Calculate the final expression Substitute the values we found into the expression $(4) + 8 - 7$. So, we have $6 + 15 - 15 = 6$.
