If x*6 and y*7-1 equal 48, what numbers are x and y?
2 answers:
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
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. (:
