Answer: 10 slices
Step-by-step explanation:
10-2-3-1=4
4+6=10
Solve the following system:
{y = x + 4 | (equation 1)
y + x = 2 | (equation 2)
Express the system in standard form:
{-x + y = 4 | (equation 1)
x + y = 2 | (equation 2)
Add equation 1 to equation 2:
{-x + y = 4 | (equation 1)
0 x + 2 y = 6 | (equation 2)
Divide equation 2 by 2:
{-x + y = 4 | (equation 1)
0 x + y = 3 | (equation 2)
Subtract equation 2 from equation 1:
{-x + 0 y = 1 | (equation 1)
0 x + y = 3 | (equation 2)
Multiply equation 1 by -1:
{x + 0 y = -1 | (equation 1)
0 x + y = 3 | (equation 2)
Answer: x = -1 y = 3
