(3x+1)/(3x+2) = (x+2)/(x-5)

jonny [76]

Answer:

x = -9/22 or -0.409 to the nearest thousandth.

Step-by-step explanation:

Cross multiplying we get:

(3x + 1)(x - 5) = (3x + 2)(x + 2)

3x^2 - 14x - 5 = 3x^2 +8x + 4

3x^2 - 3x^2 - 14x - 8x = 4 + 5

-22x = 9

x = -9/22

Give the values of a, b, and c needed to write the equation's general form.. (5 + x)(5 - x) = 7. A = 1; B = 0; C = -18. A = 25;

Licemer1 [7]

The general form of an equation is $A x^{2} +Bx+C=0$ . Solving for (5+X)(5-X)=7 by multiplying the factors and subtratcting 7 on both sides gives the equation $x^{2} -18=0$ , so
A = 1
B = 0
C = -18
