Explain please
To evaluate the expression 1/3x + 1/4 for x = 3/4, you can substitute the value of x into the expression and simplify.
Step 1: Substitute x = 3/4 into the expression 1/3x + 1/4.
1/3(3/4) + 1/4
Step 2: Simplify the expression.
1/4 + 1/4
= 2/4
Step 3: Further simplify the expression if possible.
2/4 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 2.
