If x = 2y then solve 5y-x in terms of y find the values of these expressions when y =2​

It is 6

Step-by-step explanation:

substitute x with 2y :

factorise out y :

when y is 2 :

1/2*qr*rs

step-by-step explanation:

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
