Answer:
Y = 1/4x-1
X = 4y-1
Step-by-step explanation:
layout the equations :
x+1/y = 4 y+1/x = 1/4
solve the equations, remember to switch sides switch signs solving the equations will give us the value of the letter
x+1/y = 4
x+1 = 4y
x=4y-1
***
y+1/x = 1/4
y+1 = 1/4x
y = 1/4x-1
S + 24 = 90
This is a one-step problem. so, all you have to do is subtract 24 on both sides:
s + 24 - 24 = 90 - 24
s = 66
Check your work:
66 + 24 = 90
90 = 90
Hope this helps!!
