If x varies directly with y, then :
● Increase in x results in increase of y
● Decrease in x results in decrease of y
● It is represented by : x ∝ y
Here : x₁ = 6 and y₁ = 15 and x₂ = x₂ and y₂ = 20
Substituting the values we get :
<u>Answer</u> : x = 8 when y = 20

10(3x+2)>7(2x-4)
Use the distributive property:
30x + 20 > 14x -28
Subtract 14x from both sides:
16x + 20 > -28
Subtract 20 from both sides:
16x > -48
Divide both sides by 16:
x > -3
The inequality is X > -3
