Question

Solve 0.30x+6y=300 for x

Answer 1

x=20

Explanation:

Subtract 6y from both sides:

0.30x=300−6y

Divide both sides by 0.30:

x = 300 - 6y/ 0.30

Factor out the common term 6:

x = 6 (50 - y)/0.3

Simplify:

x = 20 (50 - y)

x = 20

Hope this helped : )

Answer 2

`x=1000-20y`

Explanation:

`0.30x+6y=300`

To solve the equation for x we need to get 'x' alone

First we remove 6y from the left hand side

Subtract 6y from both sides

`0.30x+6y-6y=300-6y`

`0.30x=300-6y`

Divide both sides by 0.30

`x=1000-20y`
