Answer:

One

Step-by-step explanation:

3x-5=-3 add 5 to each side.

3x-5+5=-3+5 simplify.

3x=2 divide each side by three.

3x/3=2/3 simplify

x=2/3

The sum of two numbers is 30. If three times the smaller number is equal to two times the bigger one, find the numbers.

MAVERICK [17]

Let the smaller number be x and the bigger number be y.
Therefore, 3x = 2y $= > x = \frac{2y}{3}$ $x + y = 30 \\ = > \frac{2y}{3} + y = 30 \\ = > \frac{2y + 3y}{3} = 30 \\ = > \frac{5y}{3} = 30 \\ = > y = \frac{30 \times 3}{5} \\ = > y = 18$
Therefore, the smaller number = 30 - 18 = 12
