Question

Solve the equation X/3+1=7/15

Answer 1

$\frac{x }{3} + 1 = \frac{7}{15} \\ \\ = > \frac{x + 3}{3} = \frac{7}{15} \\ \\ \: \: \: \: \: \: \: \: (cross \: \: multiplication) \\ \\ = > 15(x + 3) = 7 \times 3 \\ \\ = > 15x + 45 = 21 \\ \\ = > 15x = 21 - 45 \\ \\ = > 15x = - 24 \\ \\ = > x = \frac{ - 24}{15} \\ \\ = > x = \frac{ - 8}{5}$

Answer 2

Answer:

-8/5

Step-by-step explanation:

X/3+1 = 7/15

X/3 = 7/15 - 1

X/3 = 7/15 - 15/15

X/3 = -8/15

by cross multiplying,

15X = -24

X = -24/15

X = -8/5
