Question

Solve and verify 9x/7-6x =15​

Answer 1

Answer:

x = - 3.182

Or

x = 1.061

Step-by-step explanation:

The question can be like this :

$\sf{ {\dfrac{9x}{7}} - 6x = 15}$

→ $\sf{ {\dfrac{9x - 6x(7)}{7}} = 15}$

→ $\sf{ {\dfrac{9x - 42x}{7}} = 15}$

→ $\sf{ {\dfrac{- 33x}{7}} = 15}$

→ $\sf{ - 33x = (15)(7)}$

→ $\sf{ - 33x = 105}$

→ $\sf{33x = - 105}$

→ $\sf{x = {\dfrac{- 105}{33}}}$

→ x = - 3.182

The question can be like this :

$\sf{ {\dfrac{9x}{7 - 6x}} = 15}$

→ $\sf{9x = (15)(7 - 6x)}$

→ $\sf{9x = 105 - 90x}$

→ $\sf{9x + 90x = 105}$

→ $\sf{99x = 105}$

→ $\sf{x = {\dfrac{105}{99}}}$

→ x = 1.061

Answer 2

Answer:

35

Step-by-step explanation:

9x / 7 - 6x = 15

9x- 6x = 15×7

3x = 105

x = 105/ 3

x = 35
