Question

Solve the equation x+3 / 2 = 3x + 5 / 5
Which method of solving for the variable could be used instead of cross multiplication?

Answer 1

Answer:

use addition and substraction method:

$\frac{x + 3}{2} = \frac{3x + 5}{5}$

$\frac{x + 3}{2} - \frac{3 x + 5}{5} = 0$

$\frac{5(x + 3)}{5(2)} - \frac{2(3x + 5)}{2(5)} = 0$

$\frac{5x + 15 - 6x - 10}{10} = 0$

$5x + 15 - 6x - 10 = 0$

$- x + 5 = 0$

$- x = - 5$

$x = \frac{ - 5}{ - 1}$

$x = 5$

Answer 2

Answer:

1/4

Step-by-step explanation:

x+3/2=3x+5/5

3/2-1=3x-x

1/2=2x

x=¼
