Question

9x/7-6x=15 equations​

Answer 1

$\frac{9x}{7} - 6x = 15$

Take lcm

Which is 7

$\frac{9x - 7 \times 6x}{7} = 15$

$\frac{9x - 42x}{7} = 15$

$\frac{ - 33x}{7} = 15$

Cross multiply

$- 33x = 15 \times 7$

$- 33x = 105$

$- x = \frac{105}{33}$

Both the no.s are divisible by 3

$(35 \times 3 = 105)$

And

$(11 \times 3 = 33)$

$- x = \frac{35}{11}$

$- x = 3.18$

$x = - 3.18$

Answer 2

Answer:

x= -5.

Step-by-step explanation:

Do L.CM. OF denominator of x and cross multiply it with 15

=> -33x = 105

=> -x = 5

=> x = -5
