D -e/3d + e= e, for d

navik [9.2K]

Answer:

$\large\boxed{d=\dfrac{e^2+e}{1-3e}}$

Step-by-step explanation:

$\dfrac{d-e}{3d+e}=e\\\\\dfrac{d-e}{3d+e}=\dfrac{e}{1}\qquad\text{cross multiply}\\\\(1)(d-e)=(e)(3d+e)\qquad\text{use the distributive property}\\\\d-e=3de+e^2\qquad\text{add}\ e\ \text{to both sides}\\\\d=3de+e+e^2\qquad\text{subtract}\ 3de\ \text{from both sides}\\\\d-3de=e^2+e\qquad\text{distribute}\\\\d(1-3e)=e^2+e\qquad\text{divide both sides by}\ (1-3e)\\\\d=\dfrac{e^2+e}{1-3e}$

Solve the inequality if possible 4(3-2x)>2(6-4x)

GenaCL600 [577]

Final Answer: No Solution

Steps/Reasons/Explanation:

Question: $4(3- 2x) > 2(6- 4x)$

<u>Step 1</u>: Divide both sides by $2$ .

$2(3 - 2x) > 6 - 4x$

<u>Step 2</u>: Expand.

$6 - 4x > 6 - 4x$

<u>Step 3</u>: Since $6 - 4x > 6 - 4x$ is false, we have no solution.

No Solution

mina [271]

Answer:

-12r2-9r-6

Step-by-step explanation:

-distribute the subtraction symbol to the second group of numbers

-(9r2+7r+2) = (-9r2-7r-2)

-then combine each term together (-3r2-2r-4)+(-9r2-7r-2)

= -12r2-9r-6
