1.) x - x = 5

2 3

2.) 0.5b + 3.4 = 0.2b + 12.4

3.) -3 - 4(t - 5) = 2(t + 3) +11

4.) 0.08x + 0.5(x + 100) = 73.2

5.) Raising rabbits. Before Roland sold two female rabbits,

half of his rabbits were female. After the sale, only onethird

of his rabbits were female. If x represents his original

number of rabbits, then

1 x - 2 = 1 (x - 2)

2 3

Solve this equation to find the number of rabbits that he had before the sale.

Thanks for using BrainMass.

so

1.) x - x = 5

2 3

First we get the LCD( least common denominator) of 2 and 3 which is 2*3=6

Therefore we multiply first fraction by 3 and second by 4 and get:

3x - 2 x = 5

6 6

So x =5

6

Therefore x= 5*6=30

2.) 0.5b + 3.4 = 0.2b + 12.4

-0.2b -3.4 -0.2 b-3.4

0.3 b ...
