To solve the equation x - 9/4 = -3/8, we need to isolate x on one side of the equation.
First, we can start by adding 9/4 to both sides of the equation to get rid of the fraction:
x - 9/4 + 9/4 = -3/8 + 9/4
Simplifying, we have:
x = -3/8 + 9/4
Next, we need to find a common denominator for the fractions on the right side of the equation, which is 8:
x = -3/8 + 9/4
To make -3/8 with the denominator of 8, we multiply the numerator and denominator by 2:
x = (-3 * 2)/(8 * 2) + 9/4
Simplifying further:
x = -6/16 + 9/4
To add -6/16 and 9/4, we need to find a common denominator. The least common multiple of 16 and 4 is 16, so we adjust the fractions:
x = (-6 * 1)/(16 * 1) + (9 * 4)/(4 * 4)
Simplifying again:
x = -6/16 + 36/16
Now that the fractions have the same denominator, we can combine them:
x = (-6 + 36)/16
Adding the numerator:
x = 30/16
Finally, we can simplify the fraction by dividing the numerator and denominator by their greatest common divisor, which is 2:
x = (30/2)/(16/2)
Simplifying the fractions:
x = 15/8
Therefore, the solution to the equation x - 9/4 = -3/8 is x = 15/8.
