\sf \dfrac{2b + 3c^2}{4a^2 - 2b}

Here given <u>a = 8</u>, <u>b = 4</u>, and <u>c = 16</u>

<u />

Inserting this values

\sf \dfrac{2(4) + 3(16)^2}{4(8)^2 - 2(4)}

Simplify following

\sf \dfrac{8 + 3(256)}{4(64) - 8}

Distribute inside parenthesis

\sf \dfrac{8 + 768}{256 - 8}

Add/Subtract similar terms

PLEASE HELP
LekaFEV [45]

Answer: one solution

Step-by-step explanation:

CONCEPT:

- One solution is when the final variable would be able to find a solution.

- Infinite solution is when the equations result in 0=0, meaning any number will fit

- No solution is when the equation results in both sides on equal.

SOLVE:

Given

3/4x-7=3(1/6x+1)

Expand Parenthesis

3/4x-7=1/2+3

Multiply both sides by the LCM of fractions (Least Common Multiple)

4(3/4x-7)=4(1/2x+3)

3x-28=2x+12

Subtract both sides by 2x

3x-28-2x=2x+12-2x

x-28=12

Add both sides by 28

x-28+28=12+28

x=40

Since we are able to get exactly one solution, there is only one solution.

Hope this helps!! :)
