Solve for x algebraically; (2/3x)+(4/x)=(7/(x+1))

Answers

Answer 1

Answer: $(2)/(3x) + (4)/(x) = (7)/(x+1) \n \nx\neq 0 \ \ and \ \x+1\neq 0 \n \nx\neq 0 \ \ and \ \x \neq -1$

$(2 )/(3x)+(4)/(x) = (7)/(x+1) \n\n\ (2+12)/(3x) = (7)/(x+1) \n \n(14)/(3x) = (7)/(x+1)\n \n14(x+1)=3x\cdot 7$

$14 x+14=21x \n \n14=21x-14x \n \n 7x=14 \ \ /: 7 \n \nx=2$

Answer 2

Answer: $(2)/(3x) + (4)/(x) = (7)/(x+1)$

$(2)/(3x) + (12)/(3x) = (7)/(x+1)$

$(14)/(3x) = (7)/(x+1)$

$Cross\ multiply :$

$14(x+1) = 7 * 3x$

$14x+14 = 21x$

$14x-21x =-14$

$-7x =-14$

$x = (-14)/(-7)$

$\boxed{x=2}$

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Number of friends = 8

Price of admission per person = x

Number of friends who paid an extra $6 = 4

The total cost of 8 friends.

= 8x + 6 x 4

= 8x + 24

Thus,

The totalcost is 8x + 24.
