Distributive

Step-by-step explanation:

3(x + 5) = 7x - 13   given

3x + 15 = 7x - 13   distribute

- 3x -3x   Subtraction property of equality

15= 7x - 13

+13 +13    Addition property of equality

28 = 7x  

7 7   division property of equality

4=x   simplify

x=4

the answer is 0.3175 hope that you ^w^
