State the property or identity.1) 27 + 0 = 27
2) a + 4 = 11 4 4 a = 15
I can solve systems of equations by elimination.
3.) What is the first step in solving a system of equations using substitution method?
Let's think about... x + y = 5 x y = 1
Yipee! It's "systems of equations"!
your teacher...lol
Is (14, 5) a solution for
x + 14y = 84 2x 7y = 7 ??
Solving by elimination:
2x 2y = 82x + 2y = 4
4x + 3y = 162x 3y = 8
2x 3y = 44x + 5y = 8
5x 3y = 16
4x + 5y = 2
