To solve the equation x − 9/4 = -3/8, we need to isolate the variable x.
Step 1: Add 9/4 to both sides of the equation to eliminate the -9/4 on the left side:
x - 9/4 + 9/4 = -3/8 + 9/4
x = 9/4 - 3/8
Step 2: Find a common denominator to add the fractions:
x = (9/4)(2/2) - (3/8)(1/1)
x = 18/8 - 3/8
Step 3: Simplify the fraction:
x = (18 - 3)/8
x = 15/8
Therefore, the solution to the equation x − 9/4 = −3/8 is x = 15/8.
