It looks like you've written a set of equations involving absolute values and variables x and y. To solve these equations, we'll isolate the variables and consider the cases when the absolute value expressions are positive and negative. Here's how to solve each equation:
|x| + 3 = 5:
Subtract 3 from both sides: |x| = 5 - 3 |x| = 2
Now, consider two cases for the absolute value:
Case 1: x is positive x = 2
Case 2: x is negative -x = 2 x = -2
So, the solutions for this equation are x = 2 and x = -2.
|2x| + 3 = 9:
Subtract 3 from both sides: |2x| = 9 - 3 |2x| = 6
Now, consider two cases for the absolute value:
Case 1: 2x is positive 2x = 6 x = 6/2 x = 3
Case 2: 2x is negative -2x = 6 x = 6/(-2) x = -3
So, the solutions for this equation are x = 3 and x = -3.
|y| - 2 = 1:
Add 2 to both sides: |y| = 1 + 2 |y| = 3
Now, consider two cases for the absolute value:
Case 1: y is positive y = 3
Case 2: y is negative -y = 3 y = -3
So, the solutions for this equation are y = 3 and y = -3.
