Answer:

0.629 + 0.316= 0.945

2.185 + 1.118 = 3.303

0.59 + 0.307 + 0.74 = 1.637

0.868 + 0.962 = 1.83

0.065 + 0.36 = 0.425

0.549 + 1.912 = 2.461

0.48 + 0.635 = 1.115

1.67 + 0.834 = 2.504

1.078 + 0.27 + 2.21 = 3.558

2.572 + 0.364 = 2.936

0.78 + 1.127 + 0.17 = 2.077

0.084 + 0.267 + 0.93 = 1.281

1.476 + 0.924 = 2.4

0.356 + 0.729 = 1.085

0.44 + 0.19 + 653 = 653.63

0.814 + 0.91 = 1.724

0.358 + 0.926 + 0.53 = 1.814

1.859 + 1.305 + 0.604 = 3.768

Solving Rational equations. LCD method. Show work. Image attached.

Dmitry [639]

Answer:

$b=1$

Step-by-step explanation:

The given rational equation is

$\frac{2b-5}{b-2} -2=\frac{3}{b+2}$

The Least Common Denominator is $(b+2)(b-2)$ .

Multiply each term in the equation by the LCD.

$(b+2)(b-2)\times \frac{2b-5}{b-2} -(b+2)(b-2)\times2=(b+2)(b-2)\times\frac{3}{b+2}$

Simplify;

$(b+2)\times \frac{2b-5}{1} -2(b+2)(b-2)=(b-2)\times\frac{3}{1}$

$(b+2)(2b-5) -2(b+2)(b-2)=3(b-2)$

Expand and group similar terms

$2b^2-5b+4b-10 -2(b^2-4)=3b-6$

$2b^2-5b+4b-10 -2b^2+8=3b-6$

$-b-2=3b-6$

$3b+b=-2+6$

$4b=4$

$b=1$
