Question

answer is -103/ 345 how??? ​

Answer 1

Step-by-step explanation:

X/3-2/5÷7/15-3X=-11/30

the LCM of 3,5 is 15

X/3=5×X/3×5=5X/15

2/5=2×3/5×3=6/15

(5X/15-6/15)÷(7/15-3X×15/15)=-11/30

=(5X-6/15)÷(7-45X/15)=-11/30

=15 will be cancelled

=(5X-6)÷(7-45X)=-11÷30

cross multiply

=30(5X-6)=-11(7-45X)

=150X-180=-77+495X

=150X-495X=-77+180

=-345X=103

=X= -103/345
