Answer :
When x=.3 y=9.25. Because when you substitute x into the equation you get 1.5+2y=20 and then you subtract the 1.5 and your equations turns into 2y=18.5 and you divide 18.5 by 2 and your answer is 9.25.
The value of 'y' in the equation 5x + 2y = 20, when x = 0.3 is 9.25
How to determine the value of 'y'
From the equation;
5x + 2y = 20
Make 'y' the subject of formula
y = 20 - 5x ÷ 2
Then substitute the value of x = 0.3 in the equation
y = 20 - 5(0.3) ÷ 2
y = 20 - 1.5 ÷ 2
y = 18.5 ÷ 2
y = 9.25
Hence, the value of 'y' in the equation is 9. 25
