x=-4 y=4
A. To find the value of x, we substitute y=0 and moving the variable to the left and changing the signs on the both sides of the equation. To find the value of y, we substitute x=0 and by solving the equation y=0+4
B. We need to find the value of x and y for us to enable to answer the equation.
Solution:
•y = x + 4
0 = x + 4
- x = 4
4 = - x
•y = x + 4
y = 0 + 4
y = 4
