Question

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

Answer 1

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

Answer 2

Answer:

X=6

Step-by-step 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
