To find what y is when x = 7 plug 7 into x in the equation and solve
y = 7 - 3
y = 4
When x is 7, y is 4
To find what x is when y = 1 plug 1 into y in the equation and solve
1 = x - 3
1 + 3 = x + (-3 + 3)
4 = x + 0
4 = x
When y is 1, x is 4
To find what x is when y = 7 plug 7 into y in the equation and solve
7 = x - 3
7 + 3 = x + (-3 + 3)
10 = x + 0
10 = x
When y is 7, x is 10
Hope this helped!
