Answer:
4.) y=x-16
Step-by-step explanation:
Here,
y=4,
x=20
Now,
putting the value of x and y.
or, 4=20-16
or, 4+16=20
∴20=20
X equals to 48
The work is shown in the picture. I hope this helps.
X = smaller number, y = larger number
x + y = 15.....x = 15 - y
4x = 2y - 60
4(15 - y) = 2y - 60
60 - 4y = 2y - 60
60 + 60 = 2y + 4y
120 = 6y
120/6 = y
20 = y <==== larger number is 20
x + y = 15
x + 20 = 15
x = 15 - 20
x = - 5
