Step-by-step explanation:
![\dfrac{3}{7}+t=\dfrac{20}{21}\qquad\text{subtract}\ \dfrac{3}{7}\ \text{from both sides}\\\\\dfrac{3}{7}-\dfrac{3}{7}+t=\dfrac{20}{21}-\dfrac{3}{7}\qquad\text{LCD(7, 21)=21}\\\\t=\dfrac{20}{21}-\dfrac{3\cdot3}{7\cdot3}\\\\t=\dfrac{20}{21}-\dfrac{9}{21}\\\\t=\dfrac{20-9}{21}\\\\t=\dfrac{11}{21}](https://tex.z-dn.net/?f=%5Cdfrac%7B3%7D%7B7%7D%2Bt%3D%5Cdfrac%7B20%7D%7B21%7D%5Cqquad%5Ctext%7Bsubtract%7D%5C%20%5Cdfrac%7B3%7D%7B7%7D%5C%20%5Ctext%7Bfrom%20both%20sides%7D%5C%5C%5C%5C%5Cdfrac%7B3%7D%7B7%7D-%5Cdfrac%7B3%7D%7B7%7D%2Bt%3D%5Cdfrac%7B20%7D%7B21%7D-%5Cdfrac%7B3%7D%7B7%7D%5Cqquad%5Ctext%7BLCD%287%2C%2021%29%3D21%7D%5C%5C%5C%5Ct%3D%5Cdfrac%7B20%7D%7B21%7D-%5Cdfrac%7B3%5Ccdot3%7D%7B7%5Ccdot3%7D%5C%5C%5C%5Ct%3D%5Cdfrac%7B20%7D%7B21%7D-%5Cdfrac%7B9%7D%7B21%7D%5C%5C%5C%5Ct%3D%5Cdfrac%7B20-9%7D%7B21%7D%5C%5C%5C%5Ct%3D%5Cdfrac%7B11%7D%7B21%7D)
