    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?

    can someone correct this for me please. Directions: Solve the system by substitution. x + y = 12 y = 2x this is what i did: in the first equation i substituted y for what i have in the second equation so now it looks like this: x +2x = 12 3x = 12 x = 4 now
