Question
Solve each equation.
1. p(1 + 4) - 2(p + 6) = 6
A: p = -2?
Without graphing, tell whether each point is on the graph of 2x - y = 5.
1. (1, -2)
A: Since (1, -2) is not a solution of 2x - y = 5, (1, -2) is not on the graph?

#1.
p(1+4) - 2(p+6) = 6
5p - 2p - 12 = 6
3p = 18
p = 3
the 2nd question is correct, the point is NOT on the line
p(1+4) - 2(p+6) = 6
5p - 2p - 12 = 6
3p = 18
p = 3
