Answer:
x = 12
Step-by-step explanation:
Assuming you reqire the value of x that makes
4 : x equivalent to 5 : 15
Divide 5 by 4, that is 5 ÷ 4 = 1.25
Thus 1.25x = 15 ( divide both sides by 1.25 )
x = 12
Hence
4 : 12 = 5 : 15
Simplifying the expression gives 36x^2 - 82x - 10 = 0
<h3>How to simplify the expression</h3>
Given the expression;
4x-5/3+2x=7+2/9x+2

Cross multiply

Expand the bracket

Collect like terms
36x^2 + 8x - 45x - 27x - 18x = 0
Add the like terms
36x^2- 82x - 10 = 0
Thus, simplifying the expression gives 36x^2- 82x - 10 = 0
