Answer :
Answer:
x(the bigger number) = 142
y(the smaller number) = 21
Step-by-step explanation:
set up the problem
x - y =121
(we know that y is the smaller number because the answer is not negative, therefore the second number has to be smaller.)
7y = x +5
solve for x
x = 7y - 5
insert the new value of x into the equation
7y - 5 - y = 121
solve for y
6y - 5 = 121
6y = 126
y = 21
substitute the new value of y into the original equation
x - 21 = 121
solve for x
x = 142
hope this helped! lmk if you have any questions :)
have a wonderful day <3
