Question

If the ordered pairs (x - 3,3y + 1) and (y + 1, x + 3) are equal, find x and y. ​

Answer 1

Answer:

y=3,x=7

Step-by-step explanation:

x-3=y+1

x-y=4 (equation 1)

3y+1=x+3

x-3y=-2 (equation 2)

substract equation 1 from 2-

x-3y-(x-y)=-2-4

x-3y-x+y=-6

-2y=-6

2y=6

y=3(put in equation 1)

x-3=4

x=4+3

x=7
