Solve the equation. Then check your solution.

Step-by-step explanation:
4/5+x=3/7
x=3/7-4/5
x=15-28/35
x= -13/35 option D
Answer:
(d) -13/35
Step-by-step explanation:
[tex]\cfrac{4}{5} + x = \cfrac{3}{7} \\ \\ \\ x = \cfrac{3}{7} - \cfrac{4}{5}\\ \\ \\ x = \cfrac{3 \times 5}{7 \times 5} - \cfrac{4 \times 7}{5 \times 7} \\ \\ \\ x = \cfrac{15}{35} - \cfrac{28}{35} \\ \\ \\ x = \cfrac{-13}{35} \\ \\ \\ x = -\cfrac{13}{35}[/tex]
Answer : (d) -13/35
