Answer:
x = 9/4
Step-by-step explanation:
1) Find common denominator
3x/6 + -x/6 = 3/4
2) Combine fractions with common denominator
3x-x/6 = 3/4
3) Combine like terms
2x/6 = 3/4
4) Cancel terms that are in both the numerator and denominator
x/3 = 3/4
5) Multiply all terms by the same value to eliminate fraction denominators
3 · x/3 = 3 · 3/4
6) Cancel multiplied terms that are in the denominator
x = 3 · 3/4
7) Multiply the numbers
x = 9/4
