To solve for y, you need to get y on one side of the equals sign and everything else on the other side.

You can do this by using inverse operations. For example, if you have a number that is added to y, you can subtract it from both sides to get y by itself. As long as you perform exactly the same operations on both sides of the equals sign, you don't change the validity of the equation.

Here it is simple to just subtract 3/4 from both sides to isolate the y term.
y+3/4=7
-3/4 -3/4

y=7-3/4

This leaves you with
y=6 1/4

y=6 1/4

6 1/4 + 3/4 = 7

1)
y + 3/4 = 7
4y/4 + 3/4 = 7
4y+3/4 = 7
4y+3/4 (4) = 7(4)
4y + 3 = 28
4y + 3 - 3 = 28 - 3
4y = 25
4y/4 = 25/4
y = 6 1/4 or 6.25

properly you have 2 variables so which you would be able to never understand what Y equals precisely yet you probably did do the suited element in coaching for fixing Y. Y = e ^ (2.3lnx +4.7) be advantageous to apply the Paranthesis so as which you do not purely advance the two.3lnx via e. The 4.7 needs to be secure. Then, all you're able to do is get the cost of x and you will sparkling up for Y.

u have to multiply everything by 4
then subtract 3 from both sides
then divide by four
u get
4y=25
y=25/4 i think

multiply both sides by four you get y+3=21 then subtract 3 from both sides and get y=18

y+3/4=7
y=7-3/4
y=(28-3)/4
y=25/4
