What's is the value of y in the equation 5x + 2y =20 when x=0.3

To solve this problem, we must substitute in the value we are given for x into the equation and then solve the equation for the variable y. To begin, we substitute in the value and perform the multiplication with the coefficient, as follows:

5(0.3) + 2y = 20

1.5 +2y = 20

Next, we must subtract 1.5 from both sides to get the variable term by itself. If we do this, then we get:

2y = 18.5

Finally, we must divide both sides by 2y to cancel out the coefficient of 2 on the variable y. Therefore your answer is:

y = 9.25

Hope this helps!

good luck on your studies! : )

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.
