Question

Solve the equation. Then check your solution.

Answer 1

(d) -13/35

Explanation:

`\cfrac{4}{5} + x = \cfrac{3}{7} \\ \\ \\ x = \cfrac{3}{7} - \cfrac{4}{5}\\ \\ \\ x = \cfrac{3 * 5}{7 * 5} - \cfrac{4 * 7}{5 * 7} \\ \\ \\ x = \cfrac{15}{35} - \cfrac{28}{35} \\ \\ \\ x = \cfrac{-13}{35} \\ \\ \\ x = -\cfrac{13}{35}`

Answer : (d) -13/35
