Question

If m=(3x-5)/5 and n=(x-7)/3 and 3(m+n)=13 .find x​

Answer 1

Answer:

45/4

Step-by-step explanation:

m = (3x - 5 )/ 5

n = (x- 7) /3

3 (m + n ) = 13

$3 (\frac{3x \: - 5}{5} - \frac{x - 7}{3} ) = 13$

$3(( 9x - 15) - (5x - 35)) = 13 \times 15$

3(9x -15 - 5x + 35) = 13 × 15

4x + 20 = 13 ×15 /3

4x +20 = 13 × 5

4x +20 = 65

4x = 65 -20

4x = 45

x = 45/4
