How do you solve #7+ 4y = 39#?

Answer 1

Nathan Axel

#y=8#

We have to reverse the mapping to find out the answer

Minus 7 on both sides

#7-color(red)(7)+4y=39-color(red)7#

#4y=32#

Now divide both sides by 4

#4/color(red)4y=32/color(red)4#

#y=8#

y=8

you'll want to get y by itself one one side of the equation, so subtract a 7 from both sides

#7+4y=39# subtract 7 from both sides

=#4y=32#

divide both sides by 4 to isolate y

=#y=8#

#y=8#

In order to find #y#, we must first isolate the variable. Therefore, we subtract #7# from both sides.

#7-7=0 and 39-7=32#

Now, we're left with

#4y=32#

We still need to isolate the variable. Thus dividing by #4# on both sides;

#(4y)/4 = y and 32/4= 8#

#y=8#

To solve the equation 7 + 4y = 39, follow these steps:

Subtract 7 from both sides to isolate the term with the variable: 4y = 32.
Divide both sides by 4 to solve for y: y = 8.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
