Does the point (1, 20) satisfy the following system of equations? y = -2x + 15 y = x +12 Substitute 1, in for x, and 20, in for y, into both equations. If you get a true statement, then yes, the point satisfies the system y = -2x + 15 20 = -2(1) + 15 {substituted in} 20 = -2 + 15 {multiplied} 20 = 13 {added on right} - this is a false statement, so no the point does not satisfy the system - no need to check in other equation © Algebra House
