Answer:

x < -3

Step-by-step explanation:

Step 1: Subtract 6 from both sides.

$4x + 6 - 6 < -6 - 6$
$4x < -12$

Step 2: Divide both sides by 4.

$\frac{4x}{4} < \frac{-12}{4}$
$x < -3$

Therefore, the answer is x < -3.

X^2/9+2y/7 help me solve

vfiekz [6]

So firstly, we have to find the LCD, or lowest common denominator, of 9 and 7. To do this, list the multiples of 9 and 7 and the lowest multiple they share is going to be your LCD. In this case, the LCD of 9 and 7 is 63. Multiply x^2/9 by 7/7 and 2y/7 by 9/9:

$\frac{x^2}{9}\times \frac{7}{7}=\frac{7x^2}{63}\\\\\frac{2y}{7}\times \frac{9}{9}=\frac{18y}{63}\\\\\frac{7x^2}{63}+\frac{18y}{63}$
