Answer:

x=0

Step-by-step explanation:

Key skills needed: Proportions, Cross multiplication, One variable Equations, Multiplication

1) Since this is a proportion, we need to cross multiply. A proportion is just 2 fractions equal to each other in this format.

---> Cross multiplication is when you multiply the first fraction's numerator by the second fraction's denominator, and you multiply the first fraction's denominator by the second fraction's numerator.

---> You set these products equal to each other.

2) So if we cross multiply it would be: 3(3x+5) = 5(3-2x)

---> If you multiply everything out, it would be --> 9x + 15 = 15 - 10x

3) Move the x terms to one side and the numbers to the other side

---> 9x + 10x = 15-15

4) Combine like terms (9x+ 10x= 19x) (15-15=0) 19x = 0

5) Divide by 19 and x=0.

Hope you understood and have a nice day!! :D
