Question

If x*6 and y*7-1 equal 48, what numbers are x and y?

Answer 1

Answer:

6x=48

7y-1=48 (im assuming the y is on the 7.)

48/6=8=x

48-1=47/7=6.7=y

Answer 2

Answer:

x = 8

y = 7

Step-by-step explanation:

x • 6 = 48

In order to isolate the variable, you need to do the opposite operation which is division in this case.

Divide 6 by 6 to cancel it out. Whatever you do to one side has to be done to the other side. Now we're left with 48 ÷ 6

$x=\frac{48}{6}$

$x=8$

We can check this by plugging your answer in the equation

8 • 6 = 48

This statement is true

y • 7 - 1 = 48

Start with doing the inverse operation, which is addition. Add 1 to -1 to cancel it out and do the same to the other side

y • 7 = 49

Then, divide 7 by 7 and do the same to the other side

y = 7

Check to make sure you're right

7 • 7 - 1 = 48

49 - 1 = 48

48 = 48

This statement is true

I hope this helps. (:
