Question

X:(x+4)=3:5
find the value of x

Answer 1

X=6

Explanation:

X divided by(x+4)=3 divided by 5, x=-4

cross multiply

5x=3(x+4)

Remove parentheses

5x=3x+12

move the variable to the left

5x-3x=12

collect like terms

2x=12

divide both sides

x=6

Answer 2

`x:(x+4) = 3:5\\\\\implies \frac x{x+4} = \frac 35 \\\\\implies 5x = 3x +12\\\\\implies 5x -3x = 12\\\\\implies 2x = 12\\\\\implies x = \frac{12}2 = 6`
