The value of the expression 21x + 30y is -9

<h3>How to evaluate the expression?</h3>

The equation is given as:

7x+10y=−3

Multiply both sides by 3

3 * 7x + 3 * 10y=−3 * 3

Evaluate the product

21x + 30y = -9

Hence, the value of the expression 21x + 30y is -9

Answer:

$log\boxed{7}$

Step-by-step explanation:

$log\frac{14}{3}+log\frac{11}{5}-log\frac{22}{15}$

$=log\bigg(\frac{14}{3}*\frac{11}{5}\bigg)-log\frac{22}{15}$

$=log\bigg(\frac{14*11}{3*5}\bigg)-log\frac{22}{15}$

$=log\bigg(\frac{154}{15}\bigg)-log\frac{22}{15}$

$=log\bigg(\frac{154}{15}\div\frac{22}{15}\bigg)$

$=log\bigg(\frac{154}{15}\times\frac{15}{22}\bigg)$

$=log\bigg(\frac{154}{22}\bigg)$

$=log\boxed{7}$

$6r+5=11r\ \ \ \ |\text{subtract 6r from both sides}\\\\5=5r\ \ \ \ |\text{divide both sides by 5}\\\\\boxed{r=1}\\-------------------------\\\dfrac{2x-4}{2}=6x+3\\\\\dfrac{2x}{2}-\dfrac{4}{2}=6x+3\\\\x-2=6x+3\ \ \ \ \ |\text{add 2 to both sides}\\\\x=6x+5\ \ \ \ |\text{subtract 6x from both sides}\\\\-5x=5\ \ \ \ \ |\text{divide both sides by -5}\\\\\boxed{x=-1}$
